Mikey,
It's hard to answer your post, when we know so little.
Sexuality, personally, I can't really help you with. I'm sure it's normal to be confused, but I've always known I'm straight, never had any doubts, so I've never had to have any struggles with my sexuality. There may be a topic under the Mature Forum, however. That may help you (I'm pretty sure there is a topic there, correct me if I'm wrong.)
Well I've been confused about whether I'm a tb or dl. I only really liked diapers, then I wanted to wear my onesie, be cuddled by someone, and so I thought I was a tb. Then I didn't think I was either, because I always liked pullups more than diapers, so I figured I was an LG (little girl) because I also like my frilly dresses etc... I have come to the conclusion, that I am all three. Diapers can be sexual for me on their own, I feel safe while I am acting like a baby, and I have fun while acting like a little girl. There is the TB, DL and GGLG all right there, seperate times.
It is something you have to explore, and learn about on your own... you may be many things, only one, however if you are confused more than likely you have a little bit of each thing. Again, hard to give more advice without knowing the full situation.
You may very well be going down the wrong road, and doing the right things. I don't know exactly what it is your doing so I am going to use general advice. Always remember, always, that you can change things. I have been down that road, felt like I had no future, didn't know why I was doing bad things, yet I continued to do them. Luckily, I was able to nip it in the arse before it got too bad, and I urge you to do the same. You can't move forward unless you want to, and if you are smart enough to know you are doing the wrong things, you are certainly smart enough to change those things into something good. If you don't feel you can on your own, I urge you to talk to someone.
Hope I helped, Mikey, and I wish you the best of luck!
