Last night there was a party at my ex’s house. This is how I found out.

Me: You going to the party tonight?

Her: uh yeah I live there lol

Me: it’s hosted at your house

Her: Yes

Me: NOOOOOO

Her: What’s wrong? Where did u think it was?

Me: Brian’s place or something

Her: Oh, well it’s here. I hope that’s not too intimidating for u

I ended up going and had fun, but I got really fucking depressed seeing her with her new guy. She saw me looking depressed, so she sent me a text saying

Her: You shouldn’t give up on urself so easily.

Meaning that she was worried that I was thinking about killing myself. I got embarrassed so I left the party by jumping off the porch while no one was looking, went into the woods, walked for a couple miles, and just fell asleep in the woods. I called an Uber and am back to my dorm room, but I left my wallet and IPhone charger at her place. What do I do now?
