i did something horrible

I was talking to this boy on Grindr, and we were talking and it went well but then he ended up saying that it might not work out for various reasons, and the fact is that he was scarily my type literally 100% my type, and I got really mad since I have BPD and I ended up hexing his only pet cat that night, 2 days later his cat suddenly ended up dying, a day after we ended up meeting in person which was yesterday he just wanted to tell me in person that it wouldn't work out between us, and it really hurt me and we argued for a literal hour non stop, and now he's fully gone, and i feel so much intense guilt, I've been crying so hard, I don't know what to do.
