It could be that the rude guy was berating your T for being late, does not know or care about you personally and that it is "you".

I know I took things the wrong way because of my interpretation instead of checking with T how they really were. Once my T remained sitting in the office and indicated with her hand for me to come in, instead of coming to get me in the waiting room and when I got there I made some ugly comment about her being lazy and it turned out she had sprained her ankle and was not walking on it!

We can not know what is going on with someone else, just like no one else can know what is going on with us unless we tell them. When you leave, your T does not have the ability to be thinking of you anymore because big, rude guy is right there (just like he's right there for "you" he's right there for T! She doesn't get a moment to collect her thoughts or anything).

I would remember that and tell T your experiences with big, rude guy and how he affects you; his actions are not your T's fault and she has her own experiences with him that you can't know. It is not necessarily that she likes him better but he is more forceful in forcing himself upon people, as he has you! He probably behaves similarly to T and that may be one reason he is in therapy? Maybe other people feel about him as you do, that he's too close and on top of them but he is unaware he comes across to other people that way.

Try to talk to T about your experiences and concerns in a pleasant, open manner. Your experiences are not "you". You are allowed to have your own feelings and experiences, they do not have to be like other people's. You feel crowded by this guy and that's okay, does not make you a bad, wrong, or odd person.

You wish you could call your T by her first name instead of her professional name. You are allowed to want that. Be curious about her reasons for having you call her by her professional name. I would eat too much candy I like it so well (sometime do :-) but I know it is not good for me so I do not. You can want something and not get it because the reason is better than the want. You get to decide that, it is not something someone else decides for you.
