Relatives suddenly lost contact by texting.

First of all, you should understand her feelings. After all, it's very sad to lose a loved one. Of course, your worries and anxieties are understandable. Since you don't answer the phone, don't call yet. If you care about her and worry about her, just send her a message silently. If the news doesn't come back, she can see it, so that she can always see your concern and concern, and her heart will be very warm. It would be more appropriate to be a guardian who silently encourages and supports her than to disturb her.
