I've allways been mentally healthy until this month things al went awful
Final exams, and at the same time I'm displaying a fuck tonne of symptoms for diabetes which makes exams worse as I have to keep getting up to go to the bathroom, I got a urine test and it showed a lot of corellation so soon ill have a blood test to confirm.

I'm stressed outta my mind and my most recent a level exam went abysmally, I could barely answer a thing.

All this stress built up and earlier today I think I had an anxiety attack
For like an hour I had a tight pain in my chest and then all of a sudden it welled up and I started to freak out. I was hyperventilating as deep breaths hurt, my head had this burning feeling like when your ashamed or extremely embarrassed. I felt dizzy and weak.

It eventually subsided, my gf helped me a lot with that, 
But even now, hours after I still feel a slight tightness in my chest. Is this normal?
