I really need to vent!

My husband and I moved into my grandmothers house about two years ago after my grandfather passed. We thought I would be good for her to have company and someone to always be there for her. When I told her I was pregnant with a T-shirt that read "great gma est. 2015"  she looks at my mother and husband and said that's yall problem not mine. I'm no ones great anything. Now she is a perfectly health woman. We were completely blindsided by this. We rent  the house we own and our tentant wants to renew their lease. My gma won't give me a baby room. We live in a 5 bed room house. She's been nice and appreciated everything we've done until now. I'm heart broken and feel stuck. Now my husband and I are looking for a apartment. 😔
