So sorry! For me, it really is one of the worst things to cope with. I had a final session with a therapist last week too and I'm feeling really sad about losing someone I really liked and enjoyed, who was particularly easy for me to connect with. I think it's incredibly difficult to form an attachment and have a good therapeutic relationship only to be cut off completely at the end. It's okay to feel sad right now. It is a loss. I hope this painful stage doesn't last too long for you and that you'll soon be able to look back and appreciate the good things that you experienced because of the unique nature of the therapeutic relationship.
