You are not a liability. You will find a T that can work with you. I have a part that can be very threatening to Ts too but when we found the right T that part hasn't started any trouble. The T didn't engage that part until it was able to talk to her without being threatening. There are Ts out there that can do this and you deserve that!!! Keep searching until you find the right one. Also, the Ts my protective parts have worked best with are the ones that are the least controlling and who work very hard NOT to allow dependance on them. I think the feeling of dependance is really scary for protective parts and creates the threatening postures. My current team helps me feel connected and secure and I know that I can count on them but they make sure I don't feel dependent on them.
