I have so many ways in which I looked at this. First of all-you are not pathetic. And you are worth it.

As far as the email goes-I think she's maybe testing you-to see if you could stand her reply was enough, but then you replied to her again? and maybe that's where you should have left it alone? Maybe Her telling you "no emails" was her acting in your best interest therapeutically. She may be trying to teach you something. Maybe it ties into your last session with her saying physically clinging onto her was uncomfortable for her-but she let herself be uncomfortable for you. Maybe now-she's trying to teach you that it's not going to be that way anymore-so her boundary clearly stated at least for this weekend is NO EMAILS. Like maybe she's just trying to say "Hey Chopin, I did that for you, but now let me show you a middle ground on boundaries" I dont't know... It's just my thoughts. Sorry your hurt. Process here at PC. Just type emails and save them as drafts and print them out for session-but don't send her anything until you can clear this up next session-
