Hi Sunybear,
I can see how a type A personality becoming disabled would lead to depression. But like the others mentioned, I too believe that depression has a lot to do with unresolved anger around things that have happened to us, such as the abuse you mentioned. I struggle with feeling anger towards anyone. And I’ve found that it often leaves me feeling helpless, unheard, lonely... depressed.
One of my biggest challenges in recovery has been to be a loving mother to my inner child. Once I get in the role of being a safe adult who acknowledges feelings and won’t judge or abandon, my little self feels more able to say what’s on her mind. An exercise I do is writing a letter to my inner child and then, using my left hand, my inner child writes back. A lot has come from it but like gostryter mentioned, you feeling for that little girl within you will come in time. Try not to give up on her though.

Hugs to the little girl in you. ~ Bee
