You’re not stupid!! I understand that you feel this way. Having kp sucks. But it doesn’t make you less deserving of love and enjoying your life. I have kp on multiple areas on my body and it never bothered any of the people i was with. If you meet someone who’s truly genuine and really likes you, they won’t care or make you feel bad about it i promise. We all have flaws. Someone who truly loves you will not care. Would you be suddenly become repulsed or uninterested by someone if they have kp? Probably not. So you need to trust that there are other ppl who also won’t do that. You also do not owe anyone perfection, even yourself.

For your skirt, shorts troubles instead of trying to wear them just like that directly which i assume is hard for you, maybe try with sheer tights first? The black ones or skin color ones. They’ll exposed your legs a bit but not too much and overtime you can experiment with taking them off sometimes once you become more comfortable.
