Hang in there.
Loud neighbors are a pain!
If your neighbors hold loud parties, call the police. There should be no noise pretty much after 10pm. It’s pretty much true in every town. Can’t advice re sex. How long does it last? It can’t be more than like what an hour?
Someone you knew for for 24 hours online it hardly a friend, you don’t know him at all. He could be anybody and could have 100 personal reasons to block you.
The one who promised to play but then said he couldn’t, it’s frustrating but how well do you know him? Are these people online only gamers you play with? You can’t really know what they up to outside of gaming. They might have something going on or issues or who knows
Do you see a therapist? I think it could help a lot
