MIL problems

Christin • FTM with little girl Rosalie Arabella💕
So recently my husbands grandfather passed away in a tragic car accident. Two days later my mother in law went to er for chest pains but was told it wasn't heart attack just major stress and nerves. She still tells everyone it was heart attack and decided she couldn't handle doing the funeralso it fell on me and my husband. Now she won't do ANyTHING for herself and she over reacts about everything especially if she doesn't get her way. It's been very stressful for me and I'm worried about being around all the stress being pregnant. I didn't go this past weekend and now she told my husband I'm being selfish and I should understand what she's been through. She doesn't understand how stressed out the situation makes me. Am I being weird feeling the way I do?
