Avoid people who ZAP your energy

I'm talking about the people who are always taking your time or demanding your attention and who usually don't reciprocate. 

Maybe at other times you have been patient enough to deal with this kind of people. However right now you are your priority, you are the one going through a loss. If they can't understand this and still demand time or attention from you, then you might want to put some boundaries and take some distance from them.

There's no need to have a confrontation. But also there's no need for you to over explain things, try to justify why you need time alone, or apologize for taking care of yourself.

Put yourself first.
