I Found Out I Have a Daughter?

I’m 26 and when I was younger I didn’t really have control of my life. These last few years I’ve gotten my act together and I’m definitely a different person. Well a few months ago I found out I have a daughter whose 5 years old. Her mom OD when she was 3 and she was living in foster care until recently. I got custody of her and now she’s living with me. I can’t imagine what she’s been through, and although people have told me she’s too young to remember her mom, I think she does. She seems so scared of everyone and she won’t leave my side. It breaks my heart to think that if I had known about her earlier I could have prevented what she’s been through. The foster care people said that she had never been physically abused but I think she might have. On one of the first days she started living with me she bumped over a plate by mistake and she acted like I was going to hit her. When she realized I wasn’t and that I wasn’t even mad she sort of was shaky then she gave me a hug and started crying. Her reaction made me feel so sad, I love her so much and I feel so guilty for whats happened to her. I don’t want to get her a psychiatrist or anything because in foster care she’s had to deal with people asking her questions about her mom and I think its been too much for her. She’s only 5 years old and I don’t want her to have to go through anything else. None the less, I want to help her but I don’t know how. She’s opening up to me but she just seems so afraid of everyone else. How can I help her adjust?
