Beware of Energy Vampires. They steal your energy and leave you tired and depressed. Many times they are family members or friends that are around often. The only thing you can do to protect yourself is stay away from them whenever possible.
But after dealing with an Energy Vampires a pint of Ben and Jerry's ice cream can help you feel better. But now I'll have to do some crunches and push-ups. (and probably run around 15 or 20 blocks.) NO! That is not going to happen. I'm too tired for that silliness.
Most Energy Vampires do not have a clue that they are that draining. They really don't mean to be. (At least I want to believe they don't.) If you tell them, they won't understand. And will tell you that you hurt their feelings. But they don't realize what damage they are doing to you.
Run while you can. Protect yourself. You are all you really have.
