poured out

I can't say no.

not in a sexual way or in a weird way but in serving.

I feel like I pour and pour and pour.
I love serving. it makes me happy when I can do something for some one else. but it's getting to a point where I feel like I'm not appreciated. I feel like I'm another picture on the wall. something ordinary and expected.

I feel like I keep pouring myself out to no end and for no cause. I'm not going to stop. but am I doing any good?
