OK guys, I saw a couple posts in this thread similar to mine and I found it somewhat encouraging.
Very short history: (38-42) MCAT, medical problems 1st and 2nd year, <200 USMLE Step 1, not super great 3rd year grades, mostly bad shelf scores (a couple good ones). Originally planned ~6 weeks for Step 2 studying, focusing mostly on USMLEWQB.
TLDR Version:
2 Weeks: NBME7, 200's.
4 Weeks: USMLEW Test: High 220's.
5 Weeks: NBME4, 200's. Pushed back exam. Demotivated.
7 Weeks: NBME3, 200's. Changed study strategy to content-focused. Pushed back again. More motivated.
9 Weeks: NBME6, Mid 230's. Excited. Motivated.
10 Weeks: Got sick, Pushed Back AGAIN. Ugh. Demotivated.
11 Weeks: Finally took Step2!
2-3 Weeks from now: I'll update with my score.

~2 Weeks in: Practice Test 1, NBME 7: 200's: OK, I thought, I've done about half of USMLEW and NBME 7 is notoriously hard, I bet I'm actually on track.
~4 Weeks in: USMLEW Test: High 220's: Wow, I'm actually doing pretty good (for my own goals), and I still have just over two weeks left!
~5 Weeks in: NBME4: 200's: ****, that wasn't good, and NBME4 is rumored to be the most predictive. *Pushed back exam.*
~7 Weeks in: NBME3: 200's: WTF! I studied, I finished USMLEW with ~60% first pass, wtf? *Pushed back exam again, but a lot further this time. Feeling kinda dysphoric*
This is when it finally hit me: This is the same problem that I had with Step 1 and with a lot of the shelf exams. For most people, they are reviewing knowledge they already studied and practicing their test taking skills, when they do QBank. I'm just doing questions without actually knowing anything and hoping that learning the small slice of material represented by QB is going to magically make me know stuff.
So I resolved to pick one resource and stick with it. Contrary to the popular feelings on Step2, I actually liked First Aid for S2CK. It felt familiar and concise. Not great with best next step in management questions, but good for everything else. I feel like, were I a more competitive USMLE studier, I'd want something with a stronger management focus, possibly more depth and breadth. I supplemented some sections with Step 2 Secrets, but I found that it really wasn't useful unless I had at least read the FA section. *Feeling motivated, having realized my problem.*
~9 Weeks: NBME5 ~5 days out: Mid 230's!! Yay, I feel like my preparation paid off. At this point, I had finished all of FA except for psych, OB/GYN, and EM, a little bit of secrets, and a few more sets of USMLEWQB, but mostly focused on a thorough, careful, single review of FA.
Then I got sick. *Pushed back exam again by 1wk.* *Lost some of my study motivation due to burnout.*
~11 Weeks: Took the test, finally! Did a little more studying, was averaging 80's on random all USMLEW, but I had seen a lot of the questions before, albeit not for ~1 month by that point. About 60% average on the remaining incorrects. Which makes sense. If I got 60% on the first pass and 60% on the remaining 40% then I combine the two, I should be getting about 80% correct.
Went into the test with mostly a feeling of relief: Even when you've lost motivation and aren't doing much studying, you still feel the weight of the test on your shoulders, like anything you do is bad because it's not studying.
Taking the test, I definitely felt like I had let some information slip since that mid-230's practice test. However, I had reviewed a few things after that test, so I felt like maybe I will make it up with other sections.
I should get my result back in ~2 weeks and I'll let you all know how it went. Frankly, I'll be happy with >230. >240 is probably a pipe dream, given the ~1wk of nothingness (should have studied, but I was so freaking burnt out), but I would be ecstatic if I beat the mean.
My advice to people like me: If your USMLEW averages are <65%, you need to be doing content review, not pretending that questions will magically make you smart. If you get sick, it's hard to determine whether pushing back is the right choice. I think it was the right choice for me, but sometimes I wish I had just taken the exam. I was lucky enough to be in a position where I was able to push things back, but for a lot of people that's not possible, and I'm sorry for that. Don't take the exam unless you're ready, but don't allow yourself to feel like you can always push back--the feeling impermanence of my exam date removed some of the feeling of urgency from my study period.
(I may reformat this if it is hard to read once I post it.)
Very late edit: Mid 230's. Not awesome, but a good improvement!
