OK. I agree with the way Fuzzy put it: ( in essence their incompetence has no reflection upon your worth.)

Since you are staying with your T... you need to try and discuss it further with him, even though he says he won't change. That your T has strong parameters (boundaries) is EXCELLENT! And all your parts will come to appreciate and rely upon that in the future. BUT you all do need to understand why he does what he does, the way he does.

It should be in YOUR best interest ... and you need to know that. Yes, it will feel (at least to some part of you) that you are abandoned or unsupported some or much of the time. But there is probably a part that will eventually be able to help the others realize what a good job the T is doing for you... helping you learn to take care of yourself (while you are shuffling through the memories.)

Therapy is tough work! I'm sorry you are feeling it's toughness now.

There are ways to increase (or begin) the communication process within yourself (selves...) some place, some how, where each part can express in magazine pictures, drawings, words... what THEY think of how the T is treating them... or of the stuff that comes up. ONE of you probably knows the best way your "system" can do this... try and let that part show the rest of you...

That you are able to express your anger and frustration about your T is a sign of progress. It means you feel safe enough to disagree! (even if the reasoning might not be so accurate.)

Be safe.
