I had a short time period of the "why me" line of thought. I would say I'm agnostic, but I don't think god, the universe or whatever makes up what a single person's life is going to be like. So that whole "why me" thing gets turned on its side pretty quickly and you kind of realize that while some things may be out of your control (your body's birth gender, the way your mind works, how your natural hormone levels are, who your family is, etc.) getting depressed about it or beating yourself up over it doesn't do a whole lot to help. Maybe over time you end up just getting sick of being depressed about it and you're spurred to take action to make changes (mental, physical, physical with medical assistance, etc.) But I personally don't believe there's some higher power in control of my life or actions.
Also, for me I've kind of come to the conclusion that I was born "like this" because of my mom's physical health when I was growing in her uterus. She had a very high level of testosterone. It was fluke she even got pregnant because she hadn't even had a period in like 5 years. She ended up getting appendicitis and while extracting that the doctor noticed her ovaries were completed coated over in some form of hard stuff. He cut a wedge out of each of them and then 6 months later she was pregnant with me. I think it's highly possible that because I'm still a XX (as far as I know - couldn't round up any legit chromosome test medical records ever) but was bathed in testosterone as a fetus I turned out this way. Pure science really. No mystical reason for it at all.
My take on life in general though has changed a lot over the last 20 years. There was a time when I wanted to give up and thought life wasn't worth living but I'm glad someone saved me from myself back then! I also used to be a hell of a lot angrier with the world. But now life is all about experience and adventure to me. It's about taking the good with the bad ... enjoying everything ... loving and being loved ... giving yourself to others ... helping others .... being helped yourself. There's so many things to explore and beauty to behold even amongst the ugliness in the world. There's also so much about life, the universe and everything that we don't understand. Maybe someday we will. It's a striving for understanding and enlightenment... getting to some "higher state" that keeps a lot of people going. For me, I just want to live healthy and try to make the most of it.
