Why does a person fall apart once a lightworker leaves them?

[GalTrav]

Just curious. I've been observing a friend (a lightworker). People are attracted to her like a moth to a flame especially ones who need helping the most. She's with them for awhile then their lives seem to be better because she's around but the moment it's time for her to go and help another person, these people's lives seem to fall apart. Why is that? Isn't it that when lightworkers come to our lives, they help light up our lives and when it's time for them to go then we are never left the same and for most, these lightworkers have helped raise our vibration to some level but for others it happens the other way around? I just noticed this happen to a person this lightworker was helping, once the lightworker left, this person went back to his old habits and ways and even seems to be a lost cause now.
