I skimmed through what you're feeling (it gets hard to read every post when you just want to provide some support....people also shouldn't expect you to really, I'm appreciative of any support I get). I want you to know I've really felt "unpopular" sort of lately especially. And here. People can seem awful and incredibly mean here. Almost everyone here has a mental illness and that's something everyone knows. It's difficult to understand the ins and outs of other people, especially another person's mental illness. What you'll see a lot is people skirting around topics, desperately trying to avoid truths that will turn into major stressors. PTSD is based around...actually yeah stress. that word is right in the name of that mental illness. We avoid crap. We don't want to hear it or see it. Because it will seriously increase our day to day stress levels creating more severe PTSD symptoms. So I just wanted to put that in there as a bit of explanation as to why it's okay to let things go especially in this forum/chat.
To relate to your feelings from my personal experience...I haven't seen a lot of my friends at all lately. In fact, it's been about two months with just my mother or one or so friend stopping in for a few minutes and me not really getting to do anything. I try to remind myself this is because I'm short on funds. My budget is really tight. Not only that but I had to put paying my cell phone aside for a little while, so even thought I have an alternative unlisted number, a lot of my friends don't know how to get a hold of me. That and I, kind of like you said about yourself, don't care who does and does not like me. I don't give a shit. And that makes a person strong. A lot of people don't like what I have to say about a lot of things. They also decide they don't like me because of that. Well I don't care, in general I don't like that person either, and we don't all have to like each other.
You might just be in a bit of a rut. If it's social things, groups of people, or co-workers etc, try taking the time to take a step back from those people for awhile. In the mean time maybe explore new venues and new ways of meeting new people. Because we all need to sometimes in our life.
And stay on the happyside. :D
