How to deal with a elderly people who are upset easily?

Wow, I didn't know Asian people were like that. Just kidding, every family is like that. Find something to do like you did. Don't worry about how she gives you the cold shoulder, she'll get over it. Try not to lose any sleep over it. If it's the worst thing that happens in your life, you have lived a great life. Try to put it into perspective. I know it's easier said than done, but do it anyway.
