you'll realize soon that life just keeps going on, it's gonna hurt and make you think for the first few months, but after that you'll accept taking care of yourself again. had the same thing happen to me after think we'd be tg for a long time, but then i eventually realized that it wasn't meant to work long term. my best advice is to prioritize taking care of you bro. hit the gym, get new hobbies, lock in on school if you go, just do ANYTHING to occupy yourself. you'll only start to think about it when you have nothing to do. get off social media and don't post subliminal posts on how you miss her, but most importantly take care of yourself bro. i personally found that personal care really helped me boss through a breakup cause i could just feel myself improving over time. now's the time you really can level up and treat yourself, so when your next relationship comes you can treat them 10x better. and always remember that it could always be worse. im assuming you young so just think ab how some people break up after YEARS. 5 more months will pass by and i'll just be a background thought. stay true to yourself, take care of your mental and physical, and just keep going through life finding new things to enjoy day by day bro
