Do you ever just feel like you're misunderstood--nobody gets you, only a few people (if any) care, and you're all alone?

I know that I’m going through a bit of depression at the moment, but even if I remove all of that, I feel like so many people in my life have given up on me. My family, friends, everyone. I literally spend my days/nights sitting at home alone for the most part, except for when I have my son, and when I spend time with my boyfriend about 1–2x a week.

The boyfriend and I don’t hang out with his friends because they are rude to me, and we don’t really hang out with my friends because, well, my friendships consist of people who are so diverse that I don’t have a single “core” group of friends like some people seem to. Most of my girlfriends are married and starting to have kids, and the other ones are totally single and in the party scene. I’m stuck in between. My best friend and I got into a disagreement a few months ago, and without going into more details, I went to apologize to her and she slammed the door in my face.
I’m not complaining about getting alone time, because I’ve actually learned a lot about myself by spending time alone, but sometimes I just get SO lonely. I’m always in this state of limbo because my nature is to be very outgoing, outspoken, and social. I know “everyone” but I’m not close to everyone. I just get to know people really easily, but cultivating long-lasting friendships is different. The friendships I’ve had in the past, I went through a lot of things where they weren’t able to withstand the hardships.
I know I can make new friends…and I’m trying to nurture my older friendships…but it’s just hard sometimes, seeing people out there who seemingly have so many people to just hang out with at the drop of a hat.
