Root of all my issues?

I was sexually abused from ages 8-16. I feel like a lost a huge chunk of my childhood and my sense of security and control over my life. After it ended, I put up a wall in my mind to protect myself. For awhile afterwards, I would have flashbacks (PTSD?) especially while in the shower. The flashbacks went away but I still have dreams sometimes. I've never actually talked this out with a counselor, but I've told a number of my friends about it. I've heard this type of abuse can emotionally stunt you and I feel like it could be having a negative impact on my relationships. It definitely had a major impact on my mental health, as I was suicidal for a number of years. I know I'm healthier than I used to be, but I feel like I could get better. Counseling is expensive and so far I haven't been able to find anyone in my area taking new patients and my insurance. I want to believe I can be better to myself and the people around me.
