What should you do if room mate hid how bad their mental issues are and refuses to let you use the bathroom or other parts of the house?

I don't want to break the lease but I really can't live like this.

I get bothered every day. I feel like every day They have a crisis and want me to drop everything and just want someone home they can pick on all day

Leave break the lease
Stay
