So, I've been going on with the "I give up" mentality for I think at least a week now, and where has it gotten me? Well... Results are mixed.
I still feel lonely every now and again, but I doubt that'll ever really go away. Just considering how long I've been at this.
But at the same time I've felt a bit more confident in myself, in the sense that I don't need to waste my time looking for someone. Tried that. Didn't work.
Recently I've worked on some self improvement. I guess when I stop putting so much mental energy to one thing, it starts helping out in others.
It's definitely saved me some trouble. There have been one or two new co-workers I met recently that I momentarily took interest in, but all I needed to do was remind myself that I'm not even trying anymore, and poof! Not even a hint of a second thought afterwards.
Long story short, things still aren't perfect, but getting better.
