Your conclusion of not going is reasonable. But call your mom, more times daily. Don't listen to what they say. Doing the best thing for your mom will make you stronger person in life. I have had problematic sister. Who made me cry two days later after my wedding. She called me at 7 amm and accused of me something. I had been crying daily on top of my infertility things which was new at those time. By the way, I just came back from Emergency hospital that my sister wanted me to be with her. It is 1.09 am.
I wish you the best. Just wanted to say something. Post very soon.
