Dealing with Roommate's Late Night Guests

Overstimulation is a real thing you are not getting upset for no reason. A lot of noises at once or loud noises overwhelm me as well and it’s worse at the end of the day when I’m exhausted. Like others said, I’d recommend noise cancelling headphones or even just ear plugs. They have been extremely helpful for me in these circumstances

I wear noise cancelling headphones (with or without music) around 24 hours a day. it's so helpful. I only take them off around people I KNOW are quiet or sensory friendly. I could send you the ones I have that work pretty well. there are better ones but I have not alot of money so-

have you looked into noise canceling headphones? or earplugs? they wont fix the problem of ur roommate not warning u, but they will help muffle the sound of all the people, and hopefully help ur anxiety around loud noises and yelling. best of luck :’) <3 (if u need recommendations for earplugs or headphones lmk!!)
