I don't think you are a creep. I know I often have the urge to walk to my Ts house and just sit round the corner like I used to do with the teachers I wished had paid some attention to what was going on with my life years ago but I just keep telling myself I have my T now, things are different. I have her for two whole hours a week and if I do something I could jeopirdise that.

I think you really need to have the conversation with your T that maybe your sessions need to come closer together or you need some support from her in between sessions if things get rough. Trying to make this go away on its own won't work, in my experience, it just gets worse. Hang in there and maybe writing it out would be a good plan?
