I'm going to be a senior in HS with an 8:36 2k as of two years ago. I didn't PR last winter, though I should have. I know I'm more fit than the 8:36 time. I've started a summer 2k training programme (interactive) to help with my score--I want to break 8. I tried a 2k some time ago and it didn't go so well, couldn't push through the middle 1000 though I was hitting my goal split.
Recently, I started to realize how much I truly hate erging. There isn't even a positive kickback anymore when I know I had a good workout-just relief that I don't have to do it again until the next day. I usually hop on the erg and "just do it", but today I broke down and started crying when I thought about doing my workout. I've felt like this before, and I know I'm completely burnt out from my program, especially because I didn't break between Nationals and starting erging. I feel like I'm letting down everyone by getting this way, and I'm SO scared that I'm losing fitness.

Right now I'm at 6 sessions/week with Sundays off. If I were to permanently replace one (or two) sessions with something other than erging, could I still get fit and drop seconds? What should these replacements be? I'm willing to do anything, no matter the pain or irritation, to replace the dropped ergo sessions, so PLEASE help me out before I go completely nuts.
Thanks for any suggestions
