Oh my goodness, I am sorry you are struggling so. I don't know how I would manage without my T for as long as you are. I believe firmly that being attached is a sign of good therapy, that the therapy has healing potential because the relationship includes some care and trust and dependency. I do not know what to advise you except to please keep posting as much as you need to, and see if your school can provide some sort of referral or backup plan, seeing as asking you to go without your therapist for probably nearly three months is terribly rough!
Warm wishes to you, I hope you find all the support you need in the meantime.
