I used to be very shy and my relationships showed it. I dated one person my freshman year in high school that didn't go well because I was so shy I barely talked around him.
My second relationship went well, we bonded a lot and became quite close because they helped me realize that I was a valuable person. Not that we need help with that; my previous life experiences damaged my self-esteem greatly. We won't go into them here.
My third real relationship didn't go very well at all. I thought, because they were visually impaired as well, it would be smooth. However, we encountered our own personal issue (shyness being mine) and it ended quickly.
Other factors contributed to these relationship failures, but shyness and lack of self-esteem were at the forefront.
When I started college, I became much more confident (which wasn't saying much coming from the level I was at in high school) and, as I progressed, my self-esteem grew with me. Now, I've found myself asking people out and telling them when I have a crush. (Once again, there were more factors here...like coming out and all that, but we'll brush past those and focus on albinism.) I realize it's difficult, but I've found a part of myself that is beautiful (and this is quite recently) that I had to find myself. No one can really help you with that. You have to find the love for yourself. Wow, I'm sounding cheesey, so I'll stop.
