Do you think I am unlucky in relationship and friendships?

I(21M)never thought that one day I will also try to rant about my situation..I am the guy who always try to help others in any possible way i can but yeah my life is also complicated and due to problems and responsibilities i never got the time for relationship so yeah i never dated anyone but there were situations where I genuinely thought to build a relationship and I believe in love is selfless so i become over expressive...over caring ..over loving when I feel something for that girl and yeah I never do disrespect to anyone irrespective of genders bcz i don't look good so i decided to become the person.. people like due to my character or personality but I don't know why even putting so much efforts i end up losing them so feel confused where i am going wrong I need your advice if you can tell me to do change something

Also there are traumas also bcz of my looks like I got rejected in friendships too if i met someone online they talk good after you connect with them face reveal then boom they ghost so i Stop even trying opposite gender friendships and this incident is the worst i proposed a girl and her rejection reason was that she will feel ashamed in front of people if she choose me as partner just bcz of looks... i know not everyone is same but many incidents make me believe that no matter how much good intentions i will never get the relationship or friendship..it's not like I make relationship center of my life just want to rant about it so I know if I am doing or my thinking so i can change it.
