Advice about abuse?

Kia • I'm a sophomore in college- nursing major. Im very interested in women's health! I love friends. Snap me! K_veener
So I haven't told very many people about this experience, but I was curious if anyone of you had experienced sexual abuse and how you handled it or are coping with it now? 
I'm currently 20 and just told someone about my sexual assult experience about 2 months ago. This happened when I was 15, but I was too scared to tell anyone about it until now. It has caused me so many problems lately, which is why I decided to tell someone.  I don't know what to do or how to deal with it. Also, I haven't told my mom.. Do you think I should? Any advice would be helpful!
