It likely does stem from a combination of a lack of friends and family in my life and possibly my own securities, but who knows? It's not like I can afford a therapist at this time anyways and I'm done wasting energy on trying to learn about every little flaw and "issue" I have all on my own.

It seems to affect me even on PC particularly when I post on a thread and people thank other people but not me.

It affects all aspects of my life because when nobody pays attention to me but they pay attention to somebody else, I feel outright resentment and anger. I see the person who they pay all of the attention to as a rival and everybody who pays attention to them over me as having some type of vendetta towards me.

Heck, I'm kinda angry at you right now for thanking that person who made that abusive post towards me on that marriage thread and not me, but I'll get over it.
