Hatred/Distrust of people (Social Anxiety)

The being by one's self thing can wear a person down because it gives them time to think and analyze. And if a lot of negative things have happened, then it's those things that you will focus on. They do bring a person down. People can come up with all these corny feel good slogans or tidbits of philosophical advice, but I think that someone's emotional makeup overpowers those and doesn't utilize them, as if they even could be utilized. You are not alone. That's for sure.

Sure, you should be concerned. I think you need to be more concerned, though, when it starts interfering with your school life, work life, and your closest relationships - with family and friends, meaning it is really messing with them and wreaking havoc.

I really think that what happens sometimes makes people extroverted or introverted. People who are affirmed all the time probably turn into extroverts. People who are criticized a great deal of the time probably turn into introverts. You can't argue with the fact that what happens in a person's life also shapes them and how they look at things.

So, I think you are not alone in how you feel, especially on this forum. But when it starts interfering with normal functioning, I would definitely seek help. So many people here have sought help or are receiving help.
