Are you saying that because there is a boundary that you can only email 2x day, he "took away" the safe place of therapy? I am obviously not in your sessions, but your T is saying that this very reasonable boundary is the only change. Even if that is what you're saying, you can send as many thoughts to him as you want, you can write huge long emails, you just can't send them more than 2x day. It seems like maybe your real issue is that you can't contact him a bunch of times per day and rely on getting a fast reply.

You said, "I don't feel like I can express anything to you anymore, because all you are going to tell me is you need to go to the hospital."

I may be misremembering, but wasn't this his response to one of your multiple emails? Has he ever said this to you in session? If he hasn't, then aren't you really exaggerating or misstating what he has really said to you?

You said, "It's like since you realized I'm bipolar you've treated me different. You jump to hospital stuff all the time now."

Again, didn't this "realization" by him (which was likely long before you think it was) coexist with him re-setting the email boundary? And, again, has he ever suggested the hospital outside of an email?

"All I want is for you to talk stuff out with me. It's SO hard for me to ask me for that. It's ALL I need, but it's exactly what you've stopped doing."

You just did ask for that, which is awesome. Again, if he is attempting to talk stuff out with you and you're the one refusing (in session), then you've got to take some responsibility there. It's your therapy. You have to ask for what you need. That's how it works. If you mean "talk stuff out" as "I want to email you a bazillion times a day", then that's not going to work-- with this T, or with any competent T.

I think you should stop emailing your T altogether. You can't do therapy via email. I think you can keep a journal and bring it to therapy sessions if you want to share it with him. Otherwise, I think you should expend your energy on actually doing therapy once a week or whatever and bag the email, which seems very counterproductive and dependency-making.
