my therapist dumped me

At least that's what it feels like. I'm f 19 and have been attending sessions with them for 3 years. Slowly, they've been missing more and more meetings. This last month, I was supposed to have one once a week. In total, she's cancelled/forgot about 3, and the 4th she held while driving in her car. I'm fucking pissed because it all came up after I sent an email asking her what the deal was, and she sent a voicemail back about how she needs to reinforce therapist patient boundaries... Boundaries like actually being professional???? It just hurts cause she basically said that she had no available time to have the meetings and went out of her way to habe them, but I just wish she had told me she didn't have any time.

I'm going through a lot and haven't even gotten to tell her that I started punching myself in the face again, which is a relapse to my self harming in middle school. This entire thing is fucked and she sent me this now: " I understand you are upset but I think we should communicate directly about this. I understand you won’t be working with me anymore but I think we should honor the years that we have worked together and be able to talk."

Idk it just hurts and I already have abandonment issues and I've just been crying. Any advice or nice words?
