I know exactly what you are talking about when you say Energy Vampires. I have met a few in my life. One or two are even in my family regretfully. I look to avoid them at all costs. Especially these days as I work on my own mental and physical health. Just don't need that crap.
There are many people I have met over the years that are those bright lights. Some I am still in contact with in some form or another. Some I am not and wish I was.
Right? Life is hard enough without those people weighing you down. Good people tend to attract other good people and leave a great example for others to follow, as we help to improve each other along the way.
