Diagnose me

I'm always fucking tired except I never yawn, stay up a full 15 hours and sleep the other 9 with no problem, but I still feel mentally exhausted. I can never talk to anyone anymore cause I really don't give a fuck, I like being left alone and staying totally quiet and whenever someone tries to talk to me it REALLY pisses me the fuck off. I got this weird feeling in the front part of my head that's difficult to describe, it just feels like it's really swollen or 'dead' and it often hurts like fuck. This feeling leaves me feeling quite disassociated, I feel totally apathetic, no fear in death no nothing. Whenever I get my heart-rate up my head starts hurting all over the place, feels like it's going to explode or something. My doctor thinks I have a brain abscess and am waiting for a CT scan, what do my niggas here think? 

It does actually sound serious. I mean, if a simple eye infection nearly killed me (docs said it would have went to my brain within days if I didn't get treatment) then something like that would be worrying.

After all the stuff I've heard about the brain and how a small amount of chemicals being off, or the balance being upset by drugs, I'd assume the docs would say to you "ok, ur crazy in the head d00d, so take sum moar drugs and that'll fix ya rite up. yup. well, after we try numerous different kinds on u ferst."

Call it bad experiences in life, and with seeing bad things happen to friends.
