Last year I was seeing a therapist who was the first one ive ever actually trusted and enjoyed talking to. He left the place he work at without telling me, so I never got a reason as to why he left and never got closure. The was back in october and I still think about him and what he might be doing now. How do I just let him go?? Like I know I wont ever see or speak to hin again so I should just stop thinking about it
