I think I molested someone when I was 14

So Yeah. I was about 13-14 and my mom's friend had a daughter that was about 4 or 5. Every now and then she would come and sleep in my bed with me, and on a few occasions I touched her belly and masturbated while she was asleep. There was no genital contact either way and I never did anything like that again. But It's been 7 or 8 years since and it's been eating me up more than anything else in my life. I was young but the age difference is huge. No amount of processing will change the fact that I'm the guy that did that. I've always felt weird and extremely guilty about it but only recently did I realize that I may have actually molested someone. I dont even know what I'm writing this here for. I don't know if I'll ever be truly happy with myself as a person, or even if I deserve to be.

No, you did not. Only touching her belly is not molesting. Even if you have doubts, you should not feel guilty since she probably can not remember anything.

I would say it was inappropriate, but not molestation. I don't believe she would have been harmed by what you did since you did not interfere with her or otherwise molest her. I can see why you would feel some shame and regret, but you are a kid yourself and I think you absolutely deserve to be happy as a person and allow yourself to move forward.
