Im glad you find your therapist office as a safe place I usually know right away if my therapist office is going to be a safe place just by what the therapist has for rules concerning confidentiality and so on. Then sometimes i feel a connection with that therapist right away and other times it takes time to build up trust on both the clients and therapist sides.

I have been seeing my present therapist LL now for 2 and a half years and I still find times when I cant find the right words to explain things to her even though I feel her office building is very safe and I am safe when I am with her and that both LL and I trust each other. What helps is that I write. I keep a journal and sometimes I share my journal entries with LL. Other times I write directly to her. Maybe writing is an option for you.

hang in there
