Is there an episode you dread watching on your rewatch?

The first time I watched Friends, I was a 13 or a 14 year old middle-schooler. I am finally rewatching the show, over a decade later (i am 28 now), and I still have the episodes number 3x15 and 3x16 carved into my brain. I actually dreaded these episodes so much during my rewatch. I am watching episode 16 right now and I think that now I find it even more devastating than I did when i first watched it. Having dealt with my share of heartbreak, the hurt hits so much more. Even while watching and knowing what is going to happen, I was hoping that somehow the plotline can be changed and Ross doesn’t sleep with Chloe. Ugh, that episode is such a tear-jerker. I can only imagine how emotionally draining it must have been for Jennifer and David to get through the filming of that extremely sad episode.
