The world accepting and kind??? We wouldn't have war, or racism, or homo/transphobia etc. Definitely isn't that way.

I'm not sure it's that people are blamed - not the way that you're describing it, although I can see how it would feel that way.

But unfortunately - the only person who can "fix" or change things... is the person who is unhappy with their situation. Because they're the only person who is with them 100% of the time. Does that mean it's their fault? No, not necessarily. Sometimes - like, if someone acts like a jerk, or super self-centred or bossy or things like that, then yeah they could be the cause of their own misery (and almost always without knowing it and blaming others) but other people are shy or quiet, unassertive, and then get missed.

But no one else can change things for that person. And it isn't someone else's job.

Does it seem like a catch-22? Yep. That it does.

The only thing that can really be said.... is to keep trying, and to keep trying new things.

I was shy, quiet, and withdrawn as a child. I was very unhappy and lonely, with a low self-esteem. I still have a lot of that, but I taught myself some people skills which made it easier (and whenever it was that hypomania would have set in for the first time I'm sure helped me out a lot!).

I don't see a point in trying to blame people. How does it help to blame others? How does it help to blame yourself? No one is really doing anything wrong. No one is obligated to like us, or to go the extra mile to overcompensate for someone else's withdrawal. That said, we aren't obligated to go above and beyond to try to get others to accept and like us. If you are happy with who and how you are, then stay that way and people who don't get to know you miss out. If you aren't happy, then learn some new skills and don't quit if you run into bumps along the way.
