"We all have mental issues." There is much truth in that. For all of our similarities, we are also very different, individual beings. That's why most of us value our privacy, at least from time-to-time, and some more than others. I can e totally alone, in a room full of people.
I have always been an introvert, and it use to really bother me. When I was out, I'd often drink to much to just try and feel comfortable, and just to try to fit in. It usually didn't help, and often made things worse, much worse at times.
As I grew older, I started to realize that there was no reason for me to try to change myself. I'm just me, being me, and I do it pretty damned well! lol
I've always been a very emotional, and sensitive person, which maybe isn't always looked upon as a great characteristic, at least when you're a man, but again, I've learned to love that about myself. I'm honest, and will always try to help any living thing that needs it, whether it be another person, or a hungry animal on the street. What's not to like about that? lol
Obviously, I can't speak for you, and I'm just guessing here, but at nearly fifty years of age myself, I'm guessing that you're probably younger than me. I know you've had some issues in your life, we all do, but I'd be willing to bet that you'll continue to understand and accept yourself more everyday, and start to realize just how unique and great that you really are!
You mentioned the boy that crushed your new white shoes. I can remember stuff like that from over fifty years ago, and it still affects me when I think about it. That's obviously a sign of a very sensitive person, but again, there's nothing, wrong with it.
Thanks for your very honest post.
