Hi LookingForFriends,
The fact that you have had friends doesn’t mean that you will never have friends.
None of us can possibly know what is going to happen before it has happened. We can only trust that what we have, in this moment, is enough and believe that things will get better when we feel stuck. (Easier said than done.)
I do think that it might be worth you going back to the groups with the intention of enjoying the group, rather than looking for friends. If you find friends, that’s great. If you don’t, at least you can say that you made an effort.
You are not alone in your experiences.
