Idk what to do

After being molested when I was a child by a family member I haven't been able to feel comfortable with my sexuality and be comfortable in my own skin. Even when I pleasure myself I feel guilty and disgusted with myself and I can never reach that point of orgasm because I immediately freak out and I jerk my body away and stop what I am doing. I hope this problem won't last into my adult years seeing as I am a teenager at the moment. I have no idea what to do and I'm scared. I need advice!!!!!
