I'm not going to see my dying mom anytime soon
Why don't you want to see her? Don't you get along with your mom?
No. Talking to her bothers me.
Things can be stressful between family members sometimes. However, if a family member is dying you should probably try to see them. You may feel worse in the long run if you don't, since it will probably be the last chance you have to see her.
I just really don't care, maybe I'll go through her room instead.
It's understandable that your emotions can run really negatively during these hard times, and it's wonderful to cope in your own way. But try to think of your mom, wouldn't she want to see you one last time? It would be best to just try, and make her day instead of ignoring her.
