I'm a misanthrope trying to like people, get to know people. Is this hopeless?

OK so you've Id'd what you wish to change, you have made an effort and put your self out there. As I understand it you are now dealing with with what I call, "you can lead a horse to water but you can't make them think" syndrome. Now I guess I'd say it's up to them. If they can't accept you for who and what you are then are they worth the effort??? Probably not but by you making an effort you just might find a few worth while friends. Any man put off by your confidence is not worth your time. Same goes for women. I do not have a ton of friends, by choice, and see nothing wrong with that. I have as much social life as I wish, sometimes a bit more, and am very satisfied with the large circle of "acquaintances" that I spend very little time with and the small circle of real friends I've found. My point is I am how I am, like you I make an effort to get along with people I don't really care about except that they are living, feeling people. I am comfortable in my own skin and with who I am. Without observing you in action I really can't say there is anything else you can do better. You've offered a kinder gentler version of yourself and it's up to them to have the sense to look further than just what they think they see. Having, I'd wager, a somewhat similar childhood I understand what you are going through a bit. Many people are sharks. But not all. So I wish you luck in finding those without fins, dealing with your past and in becoming a generally happier person with people. It's a tough row to hoe but I think you have what it takes to get there. Despite how difficult some people can be. Be well and may things be as they should.
