I didn't have it with my family and so I guess Ive always felt like i belong nowhere?
I had zero sense of belonging with my family apart from my older sister. I mean that literally, all the others were just people whose house I lived in. My connection to my sister wasn't so much a sense of belonging with someone else, because well into adolescence I saw her as part of myself (messed up sense of reality and identity, long story). I was also very isolated at school and had no friends before the age of 16.
I think my reaction to that might have been almost the opposite of what you say. It made me consciously decide to find some belonging, and at the same time to be pragmatic about that and accept that it's limited in various ways. Especially my own limitations - there are a very small number of people or situations that I want to belong to.
I don't mean either reaction's right or wrong. They're just different reactions, and what you've said has made me more aware of my own.
I felt it strongly in therapy groups and when I used to live in the hospital but then after its done all those people disappear and you're back to square 1
Personally, I feel that if something was there and is now lost then it means that at least I'm capable of it.
One of the pragmatic approaches I have to belonging is that I'm happy for it to be compartmentalised. I'll accept belonging that's time limited or restricted to one aspect of my life. Like my book club - I only see the people there for a couple of hours once a month but I feel a lot of connection because I love books and so do they. It's more like I belong to "love of books" rather than I belong to that group of people. When I lived abroad I felt I belonged with the group of friends I had there. But we were friends in that situation, not back home afterwards.
For me, that's OK but then I think I can have quite a detached approach and don't always see things like other people.
A therapy group is maybe a bit different from many other things. A group like that is designed to foster trust and belonging. The group dynamic is carefully created and maintained. I wonder, are there any other types of groups that you might be interested in joining that would have at least a little bit of facilitation, ground rules and structure? Groups that would be ongoing, outside trauma and therapy. Maybe something to do with a hobby, an interest, practising a skill, volunteering?
