It's every time the same!

Everytime when they need something they come to me with their problems and I shoud help them. At the beginn I thought: Okay why not? But now actually nobody cares ablut my problemes I'm just here to listen to them and when everythings alright in their live they act like they don't know me any more. And I'm so sick of it. Once I said that to a friend and then she said she isn't interessted in this shit. Now she is ignoring me I mean Hello I have feelings to I'am human to or does I know something wrong? I'm so sick off this shit I can't tell. The next time she need my help I won't text her back so she know how does it feel like to don't be interessted in this shit.
