I'll just say from my own experience... i was never happy after selling a stock that was doing well or even had SOME good days to buy more of a stock that kept failing me.
i'm not trying to scare you and i'm not selling my shares, but i will not be adding more and my average is .75 so i know how it feels to be down and out.
i'm holding on and hoping for better days. not much else i can do
