I've moved around a lot during my studies and then for work and consequently I lost all my friends. People don't keep in touch, they forget you. I still have two friends but they live in another country. The country I live in now, I'm completely isolated. Making new friends is SO HARD, especially after college. I don't think your therapist will judge you: tons of people crave friendships and are isolated. That's often why they go to therapy in the first place. Have you tried Meetup.com? It offers a wide range of activities that you can do while meeting new people, which is usually the best way to make friends. It hasn't worked out for me yet but I'm hopeful.
