It sounds like your supervisor is one of the ones that visibly hates their life. If you can’t talk to them about finding accommodations, talk to one of the people that actually wants to be there. If that person happens to be their boss or someone who is involved in your community then hey you needed someone discuss the issue with and they were being a dick 🤷♀️
You’re a person first, student second, RA third. Make sure your pro staff know that, and if there is anyone who has said something similar or offered for you to reach out if you need to, that’s a good person to contact. I hope you are able to start recovering and get the support you need from housing!
