I have been exactly where you are. I have been hurt in the most basic ways for years on end. I have been at the end of my rope many times.
Here is the hard part. The rest of your life is your own responsibility and you need to choose to have a better life in order to make it so. Not one other person on this planet can do that, only you can.
I decided he would not win. I fight flashbacks and cutting every day. I also found a very good T whom I have been meeting with for nearly 4 years and..... it IS getting better. He no longer controls my every movement and thought!! I win!!! That is what that woman meant, although from the vantage point you are in now, it is almost impossible to understand that.
I hope very much that you feel better and find your worth, because it is there for every one of us, even if it is buried underneath abuse. It is YOUR job to take control, by working on a positive mind-set, by getting professional help, meds if they are helpful to you (and take them regularly and as prescribed, I think that is the biggest mistake people make is to fight the meds or use them wrongly).
Nobody said it was easy, but that is why there are so many support groups in 3D or internet to help you while you are working on this. You need to not give up on yourself, that is the key. And in the mean time while you are working on that, we can hold your hand, ok?
