>>16405153Learn to accept yourself the way you are would be the best advice I can give. I can relate a lot since I'm a 5'9 male and have the hand size of a 5'5 girl. I've had gfs worth bigger hands than me. I don't like shaking peoples' hands and feel pretty self-conscious and judged when I meet new people or I see someone looking at me. They are very noticeably small hands.
But for the most part I just remind myself that there is nothing to be ashamed of about having small hands, and I can't control others' opinion of me. I push the thoughts of inferiority and shame from my mind forcibly whenever they come up, and after a while I think about it less and less. Even people with big hands can be miserable, so obviously if everything was physically 'right' with me I'd probably still find something to hate about myself. Knowing that, I don't see much point in changing that aspect of myself.
Hope that helps
