Well, you know I'm going to say you should ask. I think there is a way you can do it where you won't seem needy either. Just say "is there any way we could meet twice a week for a week or two, I've been processing a lot lately and wouldn't mind the extra support" and then be prepared for her to possibly say no, and if she does just say "that's ok, just figured I'd ask" and don't look devastated (this may require acting, but I bet you could prepare with a self talk right before). Good chance she'll say yes. I mean, she wants to sell her skill of therapy right, she's in business and taking clients? If she says no and you accept her no gracefully, you will not be seen as "needy."

I'm sorry you miss your old T. I know it really sucks. It might help if you start writing letters to the old T about it, just hold on to them, or send them if you want I mean what can the T do at this point, ha! But it's helped me sometimes to write it all out when there is no one to talk to, even if I never send it or show anyone.
