So, my bridal shower is Saturday, and it is being hosted by my future mother in law so she can get to know my family before the big day. I recently had a fight with my grandmother who raised me. She is 76 and recently became very ill and I nearly lost her. While she was sick she had a very low oxygen saturation and the doctor warned us this could cause the death of brain cells and possible dementia. Luckily she recovered, but with side effects. Her memory is terrible and her mood has changed completely. She has gone from being sweet and caring to vindictive and mean. She recently told me she wasn't coming to my wedding and I haven't spoke to her in a few weeks. Well she RSVP'd to my bridal shower and I'm not sure what to do? I've been a nurse in a senior living facility for several years, dealing with patients with dementia and alzheimers isn't new to me but I'm at a complete loss. I'm just afraid she is going to come to my bridal shower and cause a scene. Advise? Help
