effed,
Don't take a swing at me, but I do think it's progress.
You're not frozen, you're having a lot of feelings. They're not alot of fun; feeling angry and abandoned is not anybody's idea of a good time, but you're feeling it and are aware of it. That's a big step in my book.
I think how you're feeling makes total sense. We do get angry when people leave us (one of the weirdest parts of me about mourning a loved one is the totally irrational feelings of being angry at them for dying). But what we needed as children was a safe place to express that anger and have it understood and accepted. It's part of our development as we get older to tolerate separations better because we carry a much stronger internal sense of the relationship and a deeper trust that the person will return.
You don't have that yet (for good reason, you're working on learning it). Of course you're angry, you needed your T and she left. No it's not reasonable to expect her to not vacation and no, it isn't really about leaving you, but the end result is that she did leave you and you're angry about it. And that's ok. I went through this during a lot of my T's vacations for years.
And when we get angry, especially if it's covering hurt, we tend to devalue the relationship "fine, I don't need you anyway!" What complicates things even further is that if we have been wounded in close relationship, we often carry the belief that you should not move close to anyone because you will inevitably get hurt. And here we are, we moved closer and now we're hurt. So of course you want to run, what you're doing feels dangerous and right now it feels like that sense of danger has been confirmed. The problem is that we draw the wrong conclusion, which is that moving closer leads ONLY to getting hurt.
Your therapist can provide the safe place you should have had earlier in life, to express your anger and have her hear it and understand it and make it clear that these are your feelings and there is room in the relationship for them. I would really urge you to discuss these feelings with her when she gets back.
I'm sorry this is so hard.
