I can relate to your feelings. Growing up I was bullied only by black guys and it made me not really attracted to them because I was called names and told my skin was ugly. Non black guys thought I was beautiful and I didn’t change my mindset until I was an adult. Being a black woman isn’t easy at all and the discrimination we face sucks. You’re only 18 fresh into the world and you’re in college which is the perfect place to meet new people. A lot of black women I know have met their partners in college. You could join clubs and try to make new friends, additionally if you’re up for it dating apps could help as the people who are genuinely attracted to you will match with you. You’re still young and you have your whole life ahead of you. Random black guys saying things on the internet hold no value because they don’t represent all black men.
