Depression and Drive

So I've been depressed for three years along with other mental health issues such as anxiety, anorexia and mood swings. Before I became depressed, I didn't really care much for stuff like that because I was 13, but even now I just can't get in the mood? Masturbation or anything sexual is a bore for me and I feel as if in the future I will have problems with partners for this reason? Any help?
