I Am A Very Caring, Loving Person, Sometimes I Care To Much

This is less than a story, more of something that's been on my mind.
I want to make a difference to people life when they are down, having problems big, or little. I guess I just care to much, I know this is why I get walked all over on, and took advantage of.

Like everytime when i'm on Fb, when I see someone in disstress, I just want to message them to make sure they will be okay, but I don't always since I don't want to come off as nosy, or weirder than I am (haha)

Any advice? Also sorry im horrid at explaining, ha. ._.
