No one, because the only people in my life either wouldnt give a fuck, or would try to basically turn it into a competition ("Oh, you have X? I have X too, only worse. And also Y.").
So I internalize it and push it all down into a tight little ball in my lower abdomen, until the day comes where it becomes a cancer and consumes me.
Do you know where that tight little ball in your lower abdomen should go? Down the shitter. You don't have to internalise it. You are your own best friend.
