Anxiety is absolutely terryfying me.

On friday night I started to feel strange, I thought it was just nervousness due to the fact that I was talking to my crush (Ahem *Blush*) And a bit later I started to feel better so I didn't question it, Then at about 1am while watching tv I started shaking, I started feeling very strange and I thought it was because I was really hungry, I made some pizza rolls and tried to eat them but my stomach felt icky and I felt like I was going to be sick.. So I stopped eating them and started shaking harder, I was freaking out.. I went to wake my mother and she calmed me down a little bit, eventually the shaking subsided with time and tea.. But then I started to feel faint, I was overheated or something.. My mother said I had a fever and that I was probably sick.. I was using frozen rice to cool my head down and drinking lots of water.. I fell asleep eventually and then woke up the next day.. I was in pain, body aches all over and I had a bad headache and felt absolutely horrible.. I slept most of the day and woke up around 4:30pm for a while, I ate some bagels and was using my computer and then went back to sleep after a bit, I woke up later that night, I was feeling alright and had soup for dinner.. Later on I had chicken, I had an appetite and felt like I could eat food.. I want to mention here how weird it is that my mother said I was sick when I didn't feel sick except for the fever and the body aches.. I didn't have a cough or sneezing or a sore throat and I know that you don't always get the same symptoms, But I usuaully get at least ONE of those... Anyway.

Sunday, I couldn't stay awake at all.. Like no matter how hard I tried I was so tired, I also kept crying.. I was crying so much I don't even understand why... I couldn't eat, I only ate a little bit of a bagel and later on ate some soup but it wasn't really enough, I had diarrhea (Tmi sorry!) later on that night and then eventually went to sleep without problems.. I woke up today, I felt better.. I could actually stay awake.. I feel dizzy though, my head hurts.. I had more stomach troubles (Gas and other things..) I still haven't eaten anything because I'm scared to eat for fear of it making my stomach hurt :/ I just don't know.. someone told me it was probably stress but I've been stressed out before and haven't reacted so badly to it...

I've been drinking a lot of water and not eating enough food, Is that causing some kind of imbalance in my system that may be causing the diarrhea?

Now if only I knew what was causing the other symptoms :(
