street drugs will not help you. Im 24 and at the age of probably 18 to 22 played with street drugs. They might temporarily help the torture thats taking place in your head, but in the long run will only make things worse even if you don't realise it. Even worse when you mix with prescribed drugs. Im actually in a terrible place right now but i know that street drugs would make things even worse so my advice to you would be stick with prescribed and self help, think of how you want to feel in the future and even if it doesn't seem possible to ever feel like that, at least its something to work towards. Hope and pray that in time things will change even if they have been this way for some time. Until you have tried all the medications available as well as self help and professional help such as CBT etc if thats your thing, you would be a fool to give up on yourself and self medicate. This is a personal perspective and what i have realised in the last two years. Its a long road and can sometimes seem unbearable i know an example being i was on sertraline for two years just trying to find the right dose. Got up to max dose 200mg eventually to realise this medication wasn't for me, two years of my life experimenting with one drug to find out it was a waste of time. These things take a long time, mental health and medications isn't a quick fix be prepared for it take a very long time potentially before feeling that life is tolerable. Just don't give up on yourself until all options have been explored.
