meth would solve all your problems!
and likely give you a thousand new ones. most psychiatric drugs only work for some people or under specific circumstances, and have long, long lists of potential side-effects. the most likely thing you'd be prescribed first is one of the SSRIs, but nobody I know ever had much success with them. antipsychotics like seroquel might help but could cause more problems than they're worth... the whole SSRI thing is why I never bothered to go to a psychologist about it.
I personally get by on tramadol or low-dose benzos, but I am well aware neither is a good solution, especially if your supply stops.
I'd personally suggest talking to your doctor, and researching whatever they recommend so you know what to be on the lookout for in terms of side-effects or improvement. keep in mind they'll likely want you to keep taking SSRIs for 4-6 weeks before changing to something else because they work long-term and they want to be sure they're actually ineffective, unless you experience serious side-effects.
have you considered talking to a psychologist or counsellor? if possible, it'd be best to try to resolve the root issue.
