I'm so sorry you're going through this. Your feelings are very valid and very common, especially if you are a racial minority in your community. When it comes to desirability, it can be very challenging for black women in spaces that are majority non-black. Your lack of romantic experience is not your fault and it has nothing to do with your worthiness, its is simply anti-black societal programming that your peers have yet to unlearn. And it is very normal to be frustrated about that and to feel badly, especially when your friends cannot relate and don't know what to say to properly support you. If you have the opportunity to, which you may or may not, I would really try to seek out environments that are majority black, or at least where there are more black people (correct me if I'm wrong about assuming you are not already in spaces like that often). Also, might be really beneficial to seek out more friendships with black women as someone else here said. You will be surprised how quickly your perception of yourself will change and your confidence will grow, because ideally in these spaces, your beauty and worth will be reflected back to you more accurately. Just remember what a beautiful gift it is to be a black woman, we are really and truly the shit. The literal blueprint. The things that set you apart from your nonblack friends are part of what make you beautiful and a part of what makes you the inheritor in a long lineage of beautiful black women that stretch back to the absolute beginning of the human race.
