Roommate is constantly turning the lights off. Why???????

So do you two discuss anything else or talk at all.? Maybe she has migraines? But it’s rude if your evidently physically in the room. It’s a power play. Talk to your roommate. If you can’t compromise then talk with your RA… Since you leave the room to go elsewhere to study maybe she likes that and wants to be alone? Like Pavlov theory… She turns off the light and you leave. To me that’s telling.

If she gives you a reason that makes sense then might need to compromise and do the above suggestions. Maybe she can stay out of the room till a later time so you can study in your room longer?

Some people with ADHD and other mental health issues go through a crash at some point. They just sorta collapse and want to lay down. Does this sound familiar?

But as suggested the first thing to do is talk to your roommate. It might be a simpler resolution then you think.
