Am I psycho?

Hi guys.. I need u to figure out what's the hell is going with me, but if u going to depress me so just fuck off.

I've been waiting the whole year for this time when I go back to my home-country, Syria, to back to my college and hopefully to graduate next summer.
The flight is after tomorrow but, now I feel I just can't go there and adapt in the new atmosphere and having my exams which I didn't prepare well for them. And I feel like I want to cancel everything.
When I think about all this shits happening there, the shity exams and studying after being stopped for 2 years, it make me having headache, dizziness and like there's a voice in my head talking about every single shit happened in my life and I can't sleep well.
am I acting like a drama queen? I just noticed my silly behavior and that a symptom of a mental illness >.<
and as u just see my ideas are flawed and not organized so this is anotheeeeeeeeeeer symptom and I'm depressed but excited it the same time. OMG.. Fuck this shit >.<
So am I psycho? do I need a therapy?
