Sounds like you're racing 10-13 hours a week, not training. "a week of zone 2"?! Zone 2 should be the every-week plan. Racing every or every other week is only sustainable for so long, and certainly not for 3 months straight for most of us before we lose significant fitness. You're likely doing too much intensity (race-pace) during the week plus racing. When you are racing you are not training.
You need, at minimum, a brief off-season/transition and time rebuilding your base. There's no quick fix, the only real fix is some time down (even if its a week of nothing or very low intensity) and then build back up (Don't just return to the same old thing). Pick up hiking (or anything else long-low intensity) and trade it in to your schedule for a while and get lots of Zone 1 for a month to change it up, be able to take a look around and remember why you enjoy this stuff. Then do a month of largely Zone 1/2, at least. Then revisit a training and racing plan.
No more group stuff or very little of it, because most of the time it ends up being a race every training session. You also don't want to rely on the "peer pressure" of training.racing club stuff all the time; find your own motivation to train/race by yourself most if not all the time. Max 1-2 groups per week, cut out racing. Race for yourself, not a club so that you are not racing to someone else's expectations, just yours.
Good luck
