Difficulty bonding with others

All my life I have found it hard to build relationships with others, whether it’s with friends, family or a romantic partner. I just feel like no one understands me and I don’t belong anywhere. I have never had a stable friends group at school or at work.

Is anyone having the same issue? How did you deal with it? Do you feel like it’s negatively impacting your life?

I have been seeing a psychologist but she just asked me to accept myself. I guess the underlying reason is I lack curiosity in others. I am also very private and don’t enjoy sharing my things with others. I would try to solve everything myself. For example even if I need a surgery I would go to a hospital myself. I wonder if this personality can be changed because I feel really weird and keep getting comments about it
