When I read what you wrote, much of it struck home. I am like you, with the "not fitting into society" part. I used to try to be social, but I finally just gave up. If someone says hi to me, if I'm having a one-on-one conversation, I'm fine. But I don't feel comfortable if anyone else is there. Everyone knows I'm different. Even my own family has basically rejected me, because I don't fit the "mold" they expected me to be. (Tears in my eyes as I write this)
In high school, I didn't fit into any group. I did have 2 friends, and they were both misfits, like me.
I, too, had nose bleeds for no reason. I remember sitting in class, maybe 5 or 6th grade, doing my works, when, drip, drip, blood would fall onto my paper. I had this happen often. Also, I, too would wake up with a blood soaked pillow.
These nose bleeds stopped when I was in high school.
(As a side note, two of my sons had bad nose bleeds as children, too. One had them so bad they wouldn't stop without doctor intervention. )
I often wonder if people who are misfits in society are more prone to UFO and other paranormal experiences because we aren't so focused on "What shall I wear to the party", and other petty thoughts. We may be more focused on internal feelings, and this allows our minds to be able to sense things around us easier.
Sorry I couldn't be of more help. Just wanted to let you know you aren't alone in this world. There are more of us out there.
By the way, I was born in New York, but left before I was a year old.
