She said that I could contact her and I want to, but I don't want it to seem like I'm being needy. I don't know what I should say or even what she would be able to do for me since she isn't my therapist anymore.

Blackfeather,

I suggest you take her up on her offer. Contact her. She would not have offered contact if she didn't want to. Tell her the same thing you said in your post here. That will give her an idea of how you are feeling and what you need. She will be able to tell you what, if anything, she can do you help you out. If she can't see you anymore as a therapist, she could likely refer you to a therapist she knows.
