God works all for good but why

Sorry for the rant everyone, I’m just really lost

I know everyone’s gonna say ”God has a plan” but I just can’t see it at the moment. The person whom I loved more than anything left (you’ve probably heard it a million times) I feel like I kinda lack any support network and why would this have to happen? Someone who really liked me and always went above and beyond. Someone I could make happy and they could make me happy. And I messed it all up. Almost two months later and I still just want it all to end. I truly think no one really cares. I pray about it every day and it almost feels like I’ve been separated from God through this. Maybe my faith was only really working when I had someone who listened to me and care about me
