How fucked am I?

I am in month 17 of my 2 year postdoc, in molecular entomology in Greece. The experience has been riddled in experimental issues mostly beyond my control, some communication issues mostly in my control and my failure. I should be able to get maybe 1 or 2 first author manuscript before end of my contract. However my PI has been clear he is unhappy with my progress and wants to have a serious discussion to aee if we can find ways to improve. At this point genuinely am I just fucked?
