Anxiety or is my brain not working?

Help_m1
For the past day, I’ve been feeling strange. As I’m typing this, I’m actually so exhausted (even though I’ve slept a good 6 hours) so my apologies if some words come out in typos. About a night ago, I was stressing about school because it’s finals week and although all of my grades are fine, I was still a mess. I tired to stay up to start on a project so around 3-4 am I chugged a V8 energy drink and wasn't really drinking any water (I know my mistake). At about 5-6 am I started feeling really weird. My head started to go numb which is weird because I would scratch my scalp and was able to still feel myself scratching myself but it felt like my head was hallow and my brain was on fire. I put it off as I was just over exhausting myself so I tried to sleep. I couldn’t, for some reason I felt like I was going to die and my brain wouldn’t shut up. So I decided to go to the hospital at 7 am My aunt drove me with my boyfriend and we were all discussing what could be wrong with me. For some reason that stressed me out even more and my neck started to go numb and my hands started to feel like static. I think I was having a panic/anxiety attack but doing breathing exercises started helping a little. In the hospital, they did X-rays and tests on me and hooked me up to a bunch of wires. They took my blood and had me pee in a cup (the results were fine) they gave me 2 pills for my anxiety and 1 pill for potassium because I was low. They also hooked me up to an IV because I was dehydrated as well. I started feeling better and went home shortly after. I was exhausted and slept all day. Started drinking more water and when I woke up, I ate. That was around like 8 pm. I stayed up a little and went to bed at around 12- 1 am which is extremely unlike me. I woke up today at 9 am which is again extremely unlike me. I feel okay but could be better. The numbness never went away though and I don’t know what the cause of that is.

Earlier I washed my hair to see if I would feel anything and I did but I still felt strange. Then my head started having the burning feeling for a while but stopped. Feeling a little better now. The numbness is going away but still present. Staying hydrated is helping I’m sure.

Another thing (kind of unrelated but I’m being paranoid) I took edibles like 1-2 months ago and it kind of messed me up a little. I had a bad high but it was over in like a couple of hours. What I felt the other day was exactly like that feeling just minus the head numbing and burning. The brain fog reminded me of when I was high off edibles though and the paranoia. Is there a way that maybe that occurrence made me this way? Anxiety ridden?
