There is no point to life. If it wouldn't hurt so many people I would end it all. I have had 'schizophrenia' diagnosis for 14 years. The only time i am truly happy is when i'm on uppers.. mainly meth. i love it. but i come down for a week afterwards and makes my depression even worse. Its Sunday afternoon and i'm drunk because my girlfriend split up with me last week cause i'm shit in bed. Fuck everything. i have no reason to live.
Sounds like you have a case of the fuckits. Ive had that many times and i don't miss them
Shit get's better man that's all i can really say. If you have schizophrenia meth is certainly not going to help you at all it's going to make it much much worse. Not to mention that it will counteract the effects of anti-psychotics atleast abit.
Are you currently taking any meds for your disorder? If you have schizophrenia you really need to be taking medication under a psychiatrists orders. I have bipolar disorder and life got a fuck of alot easier for me when i found the right combo of meds. Sure i have my bad days but nothing like years ago when i was under medicated or not on any meds at all. I have been on anti-psychotics (seroquel, risperdidone, zyprexa) and they have helped me alot. In fact id go as far to say that they have on occasion saved my life.
As for the girl mess well fuck man that sucks

. Breakups are rough as fuck and i know that all to well sadly enough

. But it sounds like you to just where not meant to be and i wouldn't take what she said too personally as people shoot their mouth off when they are pissed off. There are other fish in the ocean and you'll find a woman someday that's right for you.
In regards to the drinking take it from a long time alcoholic that alcohol makes everything much fucking worse. It turns depression into a bottomless pit of despair and makes everything look far more bleak.
If you are suicidal talk to somebody about it man anyone. Call a friend or anything or if your really bad go to the hospital. Anything is better then offing yourself man. There are very few problems that cannot be fixed but once your in the ground it's kinda hard to fix anything now is it? So talk to a friend, talk to a family member or go to a hospital if you feel you need to. Just hang in there and things will get better. If a miserable sod such as myself can get better anybody can
Stay strong and hang in there
