I ended up breaking down and e-mailing her during college, disclosing a lot of things in a desperate sounding way. I regretted it as soon as I'd sent it, but her line manager e-mailed back within 30 minutes telling me the appointments available.
I then booked an appointment for December 9th, and I'm now in therapy.
I also ended up texting my T in a 'not myself' state, which was very embarrassing when it was brought up in that first session, but she told me she understood that even though I knew I was crossing boundaries, I did it anyway, which showed that I really was desperate and in need of help urgently.

I hope this answers your question
