How do I unplug but still stay connected for important phone calls or messages from family?

Log out,delete or time limit apps you dont use for those needs. You can try and organise call/message times with you family and turn off notifications from other ppl

I use my phone only for the people who mean the most to me. I don't need to answer someone who doesn't mind waiting till the next morning for a reply. Prioritizing myself and those I love first is vital.
I set certain ring tones for important people in my life so when I unplug for a certain period of time if a family member contacts me I will know it's them based on the ring tone
