I'm glad you summoned your courage and reached out to call your T.

I would never see a T that didn't allow messages or return phone calls. I haven't actually heard of one who doesn't, although there probably are some. A therapist and neglect patients in personal crisis or when they need something outside of strict session hours is a gigantic bright red flag that says "WARNING! STAY AWAY!" Therapists who can't handle the responsibility of helping patients outside of session hours should have chosen a different profession.

Reaching out when you need help prevents bad things from happening.
