The Lord is my light and my salvation, of whom shall I be afraid?

yesterday was one of the craziest days of my life. I woke up at 5:30 because I was getting my wisdom teeth removed, as was my sister. we left the house in time to get to the oral surgeon's by 6:30, our scheduled appointment time. of course it was still locked up because we were the first appointment of the day. finally, the receptionist came along and opened and we sat in the waiting room a few minutes before they called me back. I was scared to DEATH! Not only did I have zero medical history before this, but I'd also never had an IV or anesthesia. I sit in the chair, and they start trying to find a vein for my IV, and couldn't find one in my right arm (making me even more nervous). finally, they got it in my left arm, and right about the time the doctor said "You're gonna start feeling a little more relaxed..." I was out. Before I knew it, they were waking me up and moving me to a small recovery room, where my dad met me. We sat in there while my sister woke up (I got done a few minutes before her)... as she woke up she got nauseated and began throwing up every 10 minutes or so. For those of you that know, throwing up is like my number one fear/most hated thing to do in the entire world. worse than spiders or heights or even needles. so naturally that made me very uneasy, but we eventually made it home without vomit all over the car (haha?) and sat on couches and conked out. The day was going really well between around 10 and 2- Lauren had recovered from her nausea, and I was sleeping off and on with no apparent effects from any medication. Then about 2:15 I woke up and went to the bathroom... as I was washing my hands, I started feeling light-headed and realized I needed to make it back to the living room so I could sit down before I passed out. on the short walk from my bathroom back to the living room, my vision started getting dark around the edges. I remember knocking over a cup of juice that was beside the couch I'd been sitting on, then saying "Sorry, I think I knocked that cup over" to my dad. Then apparently I passed out- which is really weird for me. I've only passed out once before, and it was right after I witnessed a fellow gymnast suffer a compound break to her right arm. Anyway, I awoke later (Dad said it was about 40 seconds that I was out) to Dad patting my cheek and calling my name, and asking if I could hear him. I faintly heard him talking to a paramedic on the phone and giving them our address... the next 5 minutes is pretty blurry, but just after dad called the ambulance, our oral surgeon's receptionist called to see how my sister and I were doing. The ambulance arrived shortly after, and I started crying. "I   don't wanna go to the hospital!" I insister to my sister and dad. They calmed me down enough so I could talk to the paramedics when they came in. Dad told them what had happened, part of which I hadn't heard, involving the part where I turned ghostly pale and my eyes rolled back in my head and my whole body became limp. When he finally woke me up, my heart was pounding and I started sweating profusely, and he says my face turned really red, probably because all my systems were coming "back online" and trying to wake me from unconsciousness. Anyway, the paramedics asked all these questions about my surgery, and the anesthesia, and my medical history, and the medicines I'd been taking, then took my blood pressure, and it was super-low- 96/60 I think. my pulse was a little low, and blood-sugar was normal, but they recommended that I go to the hospital to make sure there wasn't more wrong than just a low blood pressure. They said I was stable enough that I could ride with dad if I wanted to, instead of taking the ambulance, but he was scared that I would faint again and recommended that I take the ambulance. In the midst of being scared of riding in an ambulance, with some strange paramedic guy, and no family members, I was a little bit excited, secretly. I'd always wanted to see what it would be like to ride in an ambulance, without really NEEDING one, and this was probably the best situation for me to do so. lol.
Anyway, the ambulance ride was pretty cool, given the situation. they even buckled me into the stretcher and hooked me up to an oxygen machine, and put these sticky things on my forearms and calves to keep track of my vitals, and checked my blood pressure every 5 minutes. the paramedic that rode in the back with me was extremely nice, and we talked about my degree and classes and books, and how long he'd been an EMT and I asked him if he knew a man that used to be an EMT whose kids I babysat the past two summers. Then I rode in the dinosaur wheelchair to triage (RAWR!), and back to little room #5 of the ER, where I remained for about four hours. they checked my blood pressure more, and asked lots of questions, and forced Gatorade down me (which I later threw up), and got a urine sample... all to conclude that I was severely dehydrated. I felt a little stupid having to go through all that, only to find out that it was dehydration and not some intense medicinal allergy or something, but my parents both pointed out that they were glad it was JUST dehydration, and that we knew for sure what the problem was and how to rectify that.
After they dismissed me, the day got boring again. more movies that I slept through. more juice and gatorade. more pudding and ice cream.
I guess the point of this whole story was that I didn't freak out that much. Except for my initial reaction to having to go to the hospital and ride in an ambulance, I was calm. God kept bringing scriptures to mind, such as one of my favorites to remind myself of when I'm scared: "The LORD is my light and my salvation; whom shall I fear? The LORD is the stronghold of my life; of whom shall I be afraid?" (Psalm 27:1). and He sang over me. it was weird, not an audible singing, but a song in my spirit; again, a favorite song when I'm afraid, which is Zephaniah 3:17 set to music by Glory Revealed: "The Lord your God is with you, He is mighty to save. He will take great delight in you, He will quiet You with His love. He will rejoice over you with singing, He will rejoice over you with His song!"
Thank you, God, for singing over me and keeping my spirit at peace in the midst of the craziness. Please continue healing me- "I believe You're my healer! I believe You are all I need, You're more than enough for me."
