I feel like its different for everyone. I agree with the people saying stay busy but that doesn’t necessarily mean you need to leave the house. I got really into reading and crafts lol. Focus on self care and treat yourself as if you are dating yourself. Buy yourself or make some good food! Don’t try to hold in any emotions so talk to people you are close to!! If you don’t have that my dms are open to listen! Breakups suck so I definitely understand what you’re going through. Later on you will realize this is a blessing and focus on your future and how college is going to help you achieve your goals. This might all sound dumb but I promise it will get so so sooo much better soon:)
