I used to start making T angry with me shortly after the session, then had to deal with that all week and dread the next session. (It was all in my head. She wasn't angry but I would twist something she said until I felt she was angry with me, wanted me to go away, etc.)
Then I started just getting extremely nervous several days before---outrageous anxiety, pacing, unable to sleep, tears, etc. (same fears even if I could convince myself she wasn't angry).
Now, after a year and 3 months, it's just the day of therapy I get nervous a bit. Then I remember I don't have to perform, I don't have to 'bring a topic', I just only have to go and talk about whatever comes to mind.
I try to hang onto a good, positive, soothing mental image to help me get through the nervousness. One I have is a fantasy based on reality: I see her face and I say her name: "T?" and she smiles and replies "Yes?", and I can feel her there with me.
I remember at least, that every time I feel nervous before the session, once I get there I feel wonderful and I don't want to leave.
I heard once about someone who would sing her anxiety symptoms... "My heart is POUNDing", "My stomach is NERvous." and it indavertently helped to relieve her symptoms. Can you sing?!
