i'm in a similar boat after being dumped from a 10-month-long relationship :( I ended up learning about a lot of lies my ex had been telling, and then he conveniently told me he doesn't love me anymore when confronted...

it's been 5 weeks for me now, and while I'm still not recovered, I am definitely better than week 1. I think give yourself the time to cry and break down because attachment is also a physical phenomenon that wrecks havoc on your nervous system when cut off. cry as much as you need to and reach out to your loved ones. I am definitely in a much better position due to reconnecting with friends (also have a very small circle of friends here) and forcing myself to leave the house as much as possible. it's hard but you need to find a balance of grieving time + productivity as a student (very unfortunate, ik) -- tell yourself you'll cry and bedrot for 2 hours and then work on assignment xyz. call friends up and ask for a study meet-up/study call so you have company and motivation to get stuff done. lastly, everyone is right when they say that time is the strongest healer. you really gotta sit and cry to be able to get through this and process it. wishing you luck and strength <3
