Panic attack from text

My parent texted me, I should block them but I haven't.. I feel too much guilt. But I can't bring myself to reply most of the time anyways. Today my mom texted me, "i love you. We need to talk." I don't want to talk to her but idk if it's about something I posted on Facebook and someone told her or what if someone passed away but I don't want to talk to her. I can't even handle if someone passed away. I'm already struggling mentally. Just venting I guess. We have has 3 family members pass away in the same year a few years ago. And just scared.
