Sexual abuse

When I was about 8, I was sexually abused my one of my parents close friends. It was totally random. I don't even remember how long it'd been going on. Obviously too long. I went to one therapy session. ONE! I really think I needed to go to more but I was never taken again. But ever since I started to develop (my breasts, period starting, just puberty) I've been like ashamed of my body. I'm a 14 almost 15 year old girl. I should not be ashamed of my body. I feel like I shouldnt have boobs or a period already. I'm envious of my twin because she has neither. But honestly, I don't know why I feel this way. It could be because of the sexual abuse. It's made me distant from any guys. It even gotten to the point where I'm uncomfortable around my father. Which is absolutely crazy. My dad is a nice man who would never do anything like that. He is
