I think my mom gets offended by everything
Why do you think she gets offended easily?
She loses her temper whenever trying to talk about with others
It is not good that she gets upset and loses her temper with everybody. It does seem like she might be conservative in her thinking and doesn't like to be exposed to other thoughts. It might be better for you to explain to her how you feel so that she can make changes.
I do not want to talk with her because she just gets mad. She doesn't listen, just yells.
I understand that it's stressful, but it would be better to explain to her what she's doing wrong so that she can change.
