I'm not going to call my mom when she's giving me the silent treatment
Why do you not call her when she gives you the silent treatment?
Calling her will just ruin the silence.
You should always try to remain in communication with your parents. I know things may be weird right now, but you should still try to make the effort to talk to her.
She doesn't understand how I feel.
You should explain to her how you feel. She might not understand what you are going through.
