I would say my biggest fault is that I have esteem issues. Not self esteem issues, I actually like who I am quite a bit (yeah, there are a few things here and there I'd change, but for the most part I like myself) my issues come from the fact that I am physically and mentally incapable of understanding why someone would actually like me.
At first I thought I just had some jealously issues. Like whenever I saw a girl I had a crush on talking to another guy, my brain would just be like "Oh, well why would she wanna be with you when she can be with that guy?"
But I noticed it wasn't just in romantic situations, even when it came to my close friends by brain is like "Why would they wanna hang out with you when they could go see Pacific Rim with their other friends?"
Before long I noticed it just applied to everything. I can see my server at a restaurant talking to another customer and just assume they'd rather help that customer than me.
I realize how pathetic it sounds, and it's not like I fall into any kind of depression over it. It's usually just a simple question I find myself asking, no different than asking what I wanna do for dinner that night, or what I wanna watch on Netflix.
Just for some reason my brain can't fathom the idea that anyone would want to spend time with me when they have literally any other option.
