It still hurts

I think I'm being fired. I got an email today asking when a good time would be to sit down and talk about my future with the company.
So much has happen in the past couple of months. I've been hurt by the studio owner, someone I considered a friend. I've been thinking about moving on anyway, so I don't know why this upsets me so much.
Maybe it's the perceived friendship. I feel duped. I thought we had actually become friends outside of the studio, but I've come to realize that she saw me as someone she could get something from. I didn't live up to my potential, so she is looking for a tactful way to get rid of me so I don't run out and bad mouth her business. I've come to realize the "friendship" was a lie.
Plus...there's an event this weekend. I feel like she is holding off the meeting until after that so she can squeeze as much out of me as possible. If she tells me this week she doesn't want me back in August, I might not want to perform at the party. Again, I'm just someone she can get something from.

I need to just breathe and accept it for what it is and move on.
