Anti depressants?

I'm struggling, in truth i have been struggling for a very long time, I think most of us do. My GP has me on anti depressants and anti anxiety tablets they don't do much for me at all. 

Is there anything that does help? I think that my depression is not depression but part of my autistic spectrum thing. Assuming that it is asd not depression is there anything that can make it any better? I am not sure that I can cope for much longer.
