I know its mainly down to my unbalenced life-style, taking drugs and a few other things.
We can all blame the drugs, but what is the cause of your unbalanced life-style? Why take so many drugs? Other people go through life without even considering drugs. Or they take them sometimes but most of the time not.
It's possible that it
is the drugs, of course! Maybe you just thought it was OK to take them to excess and it turned out it wasn't. Your doctor may even tell you that it's the drugs. Doctors generally do not have the time to investigate the underlying causes of our unhappiness. They're not fucking miracle workers, after all

so it is much easier for them to blame the drugs, and tell you to cut them out. Then maybe prescribe you different drugs! :D
My self-diagnosed depression hit a peak at the same time as my drug use. I can fairly confidently say the drugs are not the root cause! I was self-medicating.
I cut out the drugs, and I stopped drinking. For a week, then I spoke to my GP. It wasn't easy to get hold of my GP. In fact if it was left up to me I would have given up trying. My cousin forced the issue. It's useful to have family members who are also in the caring professions, particularly the psychiatric variety! But I'm probably unusual in that regard.
Anyway, what I'm saying is, I don't know the specifics of your case but there's a good chance that drugs are not the underlying cause. Self-medicating can help for a while. In the long run, though, the underlying cause needs sorted out.
The GP probably can't help with the underlying cause, unless it's a straightforward chemical imbalance. You probably need to speak to someone. Your GP can refer you to a counsellor of some kind. Personally, I decided the waiting list for NHS psychologists to be ridiculously long and arranged therapy privately. I am so glad I did, it is fantastic. But hopefully waiting lists in your area are not as bad.
i have an appointment with my doctor later but im thinking of not going because i know i wont fully open up about my drug use which will not help the doctor to help me.
I understand that if i stop using drugs or at least cut down i will feel better but i dont feel that is practical at this stage as iv just got off for summer. So whould i go to the doctor and not fully open up about my drug use etc and be perscribed something that probably wont benefit me? or should i just try to take it easy and see how things pan out?
this post is seeming more and more pointless the more I type but any feedback or shared experiences would be much appreciated!
Go to your appointment. Get a referral. What have you got to lose?
PS If your doc prescribes you more drugs, that may or may not work for you. It is working for me, in the short term, while I get the underlying issues sorted out.
Whatever you do, don't leave without a psychiatric/psychology referral. Drugs buy you time but you don't want to take them for ever.
