I can understand how does it feel when someone makes fun of you, especially the person whom you like a lot. But it is not in our hands to make people love us. Yes, I would like to share the lines said by Otis in the series "Sex Education", NETFLIX, season 2 that, "Love is just dumb luck. And sometimes, you meet someone who feels the same way. And then, sometimes, you’re unlucky. But one day, you’re gonna meet someone who appreciates you for who you are. I mean, there are seven billion people on the planet. I know one of them is gonna climb up on a moon for you".
So. accept it that she doesn't love you, and it is Okay. Just have a big heart, forgive her for what she did. If u won't forgive, it will stay with you. So forgive her and let her go. I know it's hard to forgive but please, do it for yourself once. And let her go. It's not easy, but it is right to do. Let her go, let go of the pain she caused.
And you can move on, you can, definitely! just learn a new hobby, focus on careers and love your parents. they are the real person who deserves your love. You've got such a beautiful world man, such a beautiful, accept LIFE. learn new things and fill yourself with love, not for that person, but for yourself. Date yourself, care for yourself, eat good, get a pet, focus on career, many things to do. just try it, try to do it. What say?
