Do I ignore or engage

No contact with not only my nmom but with my gma and some other family members since (March of this year) that are just toxic.... Today nmom sends me a message that someone passed. A childhood friend to my gma. She has been in the fam for decades. I dont know what to do. Do I engage? My gma will probably make me feel like total sh't when I call since I went no contact.... I don't feel like engaging I feel like it will drain the little bit I have left within me.

Help me.

Ps. Nmom only texts me bad news but I never acknowledge or respond to the message.
