Welcome! Believe me, recovery is possible. It may take a while and it happens in stages, but it can happen if you work at it. Like the others have said, take your time and deal with it as you can.
I've sort of broken up my own situation into three pieces: (1) bad things affecting me that happened before the sexual abuse, (2) the sexual abuse itself, and (3) the aftermath-- feelings, beliefs, actions and so on that were driven by items one and two.
One key is to recognize that you're in control of things now. It may not feel like it at times, but you have both the absolute right and the absolute ability to make sense of it all, deal with the negative feelings, thoughts, actions, and so on, and put it behind you in your own good time. You're the boss now.
Many of us realize that csa never really "goes away," in that you can't go back and un-live any part of your life. You CAN, however, get to a point where it's just part of your history and not something that's affecting you one way or the other any more. (I've got loads of work left to do myself, but I'm on this path and doing quite well.) What's more, you'll come out of it knowing a tremendous amount about yourself and people in general. In other words, you'll gain wisdom.
One final thing: DON'T BE AFRAID OF DEALING WITH THE UGLY STUFF. Sometimes when you feel like crap and things don't feel like they're moving forward is when you make the best realizations about things. I've been making all my best progress at times when I've felt bad. Ugly can be good.
I'm sorry you had to seek MS out, but glad you found it. We're all behind you one hundred percent. Reach out as you need to.
