Does your therapist allow out-of-session contact via email? I'm guessing not, or you would probably have emailed her.

Normally, I think a client would call their therapist in a case like this. Unless your therapist has said she doesn't allow it, that would be my first thing to do.

I'm hoping that someone who has experience seeing campus counselors will answer this post. If you do end up talking to a campus counselor, you could summarize what's going on with you without discussing suicidal ideation or self-harm. Other people may say that's a bad idea.

I think you're probably going to have to either talk to your campus counseling center or find their guidelines written down somewhere (maybe on their website?) to tell you what their rules are about discussing certain subjects.

I'd like to say that the progress you had made is not necessarily gone. Sometimes we have setbacks and it's not accessible to us, and that can be very frustrating. I'm having a period like that at the moment myself.

Sometimes events just knock us off-course for a bit. When a little time has passed, and you've had a chance to discuss and digest what has happened, I hope that you'll find that your progress is still there.

Hugs.
