I'm bad with change and endings and basically therapy!

My main questions are purely simple things like - do I have to say I've arrived? How will you greet me? Can I not pay at the front desk? None of those things I did before on agreement with my previous therapist because I found receptionists changed and I didn't like saying my name out loud or being in too close contact to them. I know that sounds wierd but I get anxious easily and I prefer to slip in and out without anyone knowing, if I can. A response may help me but what if I ask too much and she thinks it is all a bit lame? Besides I have no idea what I feel right now and wonder if asking questions gives her power etc. I over think don't I?!

I'm sad all the time so I hope this eases the stress and doesn't add to it. Very nervous!
