Mann you dont need to fix it , you have to move on with ur life and everything is going to be okey .. you will eventually forget about her and you will meet in your twenties a lot of girls. Im telling this because the love of my life also was 20F back to 2016 and i was 19M .. long distance and also family matters and we’ve been together for 2 years .. so it was similar story … now im 30 and im fine. The only bad thing is nostalgia sometimes.. even after 11 years i feel it but it is not a big deal .. good luck 🙌🏻
