Apologies for the long post.
I'm mid 40’s and do not have a single close friend.
I'm not in touch with any of my childhood friends - I was sent to a different high school due to horrendous bullying and soon lost touch.
I'm not in contact with any high school friends - I always had large friendship groups but it was very fluid and when I split up with my high school boyfriend, he got the friends (all my friends were dating or very close to his friends so saved any difficulties).
Made very few friends in uni - was still with high school boyfriend throughout most of uni so wasn't as open to meeting new people as I should have been. Only in touch with one person from uni (which still equates to 50% of the friends I actually made there!)
Through hobbies I have made friends but I moved about 40 miles away several years ago and again, drifted away from those friends and the hobby.
I took up a new hobby a couple of years ago and have met loads of lovely people. If I arrange things there is always loads of people who are keen and come along but no one ever reciprocates. In fact, I'm often excluded from their arrangements with a subset of the larger group.
No one ever just messages me to check in or to make plans.
I'm not the most outgoing person and can be quite guarded with people I don't know but once I do know them I think I'm nice enough and always keen to hear about other people and have good, often deep conversations.
I don't get on with everyone - I'm never mean or nasty but can usually pick up quickly if I'll get on with someone.
I am also more guarded/sensitive than I want to be - due to the horrendous bullying I've experienced, I'm quick to turn away/take offence/feel hurt if people don't act the way I want them to towards me and I know that has been a massive factor for me as I will very quickly retreat inwards in these circumstances - by that I mean cease reaching out to them or being more reserved/guarded (never mean) and in those instances no one has ever reached out to me which just compounds the whole situation as I then feel as though I was never important to them in the first instance. I am also probably not proactive enough at reaching out to others either due to fear of rejection (or my perceived rejection).
It's a bit of a vicious cycle and I'm not sure if it's all me or a combination of my sensitivity and the type of people I've befriended? I suspect it's all me but does that make it easier or harder to solve?
Is there any point even trying to fix this at this age? Or am I just too complicated and difficult at this stage in life to even bother trying? It feels like most people already have their close friendship groups and aren't really looking to let anyone else in.
