I think we all need attention. The difference is, some people go about seeking it in healthy ways such as asking directly for what they want and need.

The rest, well, I think the rest is like it was put in the above thread, they don't know how to give themselves the self-care they need. For others it could be feeding their narcisissim...seeking attention for their egos by hurting others.

I would avoid the unhealthy ones because you are right, it will suck all the emotional energy right out of you.
