Out of the year I've been seeing my T it's happened maybe 4 times.

1st time - I didn't want to go but ended up going anyways, didn't even tell T how I was feeling about the session

2nd - 3rd time - I just cancelled and made the appointment a week after. I did tell T that I did not want to go because I was having a rough week, and T was fine with it

4th time - I emailed my T 2 days before the session saying how I had the urge to cancel but wasn't sure what to do, T ended up convincing me it would be best to go

I have a session next week I dont want to go to but it's probably going to be the most important one.

Goodluck with yours!
