new here- hoping for some help

hey guys! i've had anxiety all my life, but was diagnosed with GAD as of three months ago. it's a long story, really, but eventually it led me here and i'm hoping to talk to some people who understand or could give me a different outlook on the way i see things.
so as i said before, i've had anxiety since i was young: it started with the fear of the toilet overflowing then moving towards a HUGE fear of my teeth falling out, causing me to not eat or swallow or talk. each fear eventually goes away with time- the fireworks, fear of throwing up (that one was AWEFUL but it wasn't persistent), and even tornadoes. recently, however, i had developed a fear of passing out. it started with one of my friends who has a condition where she can't stand for long periods of time without passing out... not to mention she never ate, NEVER slept, and was involved in sports. i was always nervous about it, sure, but one time i was actually there when she fainted, and i proceeded to, by the day, become more and more terrified of it. she was out for minutes, and one time, she was out for forty five. i didn't know it would bother me until it took over my life. skipping forward, i feel all of the anxiety symptoms all of the time. when i drive, its worse because im afraid of hurting other drivers. i force myself to eat every three hours and drink ten bottles of water a day. it's safe to say iv'e eaten little to no junk food except when im driving and pull over to get some fries.
i'm really excited to be here and happy to see what everyone will say- and i'm hoping to keep updated? much love <3

hi SC!
so basically it got better after a month- i was able to wear my hair down and wear sweaters outside and wasn't worried about overheating and i went a whole week not worrying about getting less than nine hours of sleep. then one day, i got a new symptom - i was at the beach and started noticing that if i looked at the sand, it would look like static- flash, even. then i gradually got panicked and the sky even started to flash and i had to sit down and eat some grapes. it went down and i felt much better after twenty minutes or so, but after that day, i couldn't stop looking for the static and it got to the point where it became a habit and it was everywhere. when i would go outside, i would see black spots and floaters in my vision and no matter how much i told myself that it was just stress, they wouldn't reside. then, college started and i felt well at first... i ate my lunch outside and read a book and waited for classes and all seemed well. then i felt a little lopsided and got medicine head from my medicine (i didn't even feel like i was in my body) and it led me to panic. i, for some reason, couldn't tell myself that i wasn't passing out, and that it was just me overthinking as usual. i had plenty of water, plenty to eat, and wasn't sleep deprived. i've even done all the blood work to test out: i'm not hypoglycemic, diabetic, anemic, or any other condition that would give me a reaosn to pass out. however, it got to the point where the health department wouldn't let me continue classes. so as of now, im not in classes and hoping to return by spring. however, i still get panicked more often than not. when i drive, even though im sitting, i'm convinced ill drive off the road. when i stand, i try to hold on to things. i know it's crazy for me to be this anxious at such a young age, but hopefully i'll eventually come to my senses and stop being so afraid. (also that was super long oops)
