{{ambers}} I really feel for you, there is so much our mother's could have done to make us feel confident. But they didn't , and you know what, I think you, realizing how you see yourself and how you behave, it's just a way of start you own healing process.
Now, you know better. Just work on finding things that you are good at and try to use them in the right way. The feeling of accomplishment can be reached when you try and you do it for you own good.
Hang in there, PM me anytime~
