Why is it when anyone ever needed me I was there for them

Simple! People don't think you need any help you are strong and can handle your self, they think your fine you don't show you need help.

I've had it remarked to me by friends/family members that I'm better to talk to than therapists they've seen. I'm always the first one to offer a ear to listen to someone vent. The problem for me is I can sense when someone is having a hard time and needs to talk to someone, even if I don't know them. Just an energy they give off. I like to take it upon myself. I actually kind of feed off the energy initially. The problem becomes for me when these people stick around and their entire life scope of problems becomes my problem by default. It really feels like it emotionally eats me alive. Luckily I have a couple really good friends I can vent to as well. So that would be the first thing I suggest. To me listening to peoples problems offering advice and just being there depending on the conversation can be akin to mental/emotional sex.
