some wounds not even time can heal. you're not going to get over her. but you can move on. first off, no one is perfect. just look for some girls that you're even a little interested in and maybe see if there's something there. don't get too attached to one girl, cause they're not all going to say yes. the biggest thing is that you need to learn that other girl, isn't the only one in the world. you may feel like she's the only one for you, but that feeling will pass if you just put yourself out there. if you can't find anyone you like, then what you need is a hobby. clearly she's still on your mind, so you need to get your mind on something else. it won't be quick, and you're gonna need to take baby steps with this. first make her less of something on your mind. then, bring a new person into the mix. it doesn't have to be someone you love or even really like. it could just be a friend that you care about. then, find someone you like. try hanging out with her, then ask her out on a date. take it slow, and don't get attached right away. give it a few before you let your guard down, and slowly let yourself fall in love. treat it like going into a cold pool, you go in slowly, then after you're fully in, move around a little, and soon it'll warm up. you'll still miss the other girl, but she'll be just a fond memory, instead of a haunting presence like she is now. good luck man, and i hope things work out for you
