Starting to Stress Out?

I just came back to Terengganu yesterday afternoon (after two weeks of paradise).

I unpacked and do most of the housework yesterday so that I can sleep late today. But surprisingly, I woke at 7.40am. Who woke before noon during weekends? 

I woke up and my brain ran full turbo in panicked and depression. Unfinished tasks pop-up one by one and I start freaking out. I am not sure whether I am on track or lost in mid-way with my research, with my PhD. I got a friend studying with me and he finished his chapter 1, 2 and 3 already. And he is like halfway finished. He attended 3 conferences, wrote 4 journal papers. 

Me, my Chapter 1, 2 and 3 are like quilts, only have woven. Attended one conference, wrote 2 paper (but only 1 accepted).

My excuse is "I GOT LABS TO RUN". 

I completed two different chemical analysis for my samples and now I planned to pause a while and write thesis and papers and analysis. I aim to spend me November and December doing all these. But November is half gone. I got seminars and poster presentations queing up. Can I finish them on-time?
