I think I am dying

My boyfriend just broke up with me. Super unexpected but I could tell his vibe was off and he was losing himself a little. Basically said he needed to work on himself and wanted to do so before I ended up hating him. I get it, but right now I wish I hated him so I didn’t have to feel like this. I literally feel like someone flipped my world upside down like how am I supposed to go about my life like this I feel like it will never get better😔
