My suggestion don't over think "do I do cardio x amount or do I do weight x amount" I think you should do "what you love" make your workout the fun stress free part of your day to relearn the habit
The last time I fell off the wagon so to speak was 2012. My mom had cancer and my dad had a stroke 10 years ago, diabetic, dementia you name it he suffers from it. I moved them in with me since there home was 3 hours away. My mom survived but I'm still taking care of both of them just not in my own home. The stress of having them in my home along with my dh that hates how they use me depend on me and not my siblings anyway long crappy story.
I'm one of these when I get stressed I shut down. I started having weight fall off so I was looking good
but I wasn't doing cardio, weights or eating enough and what I ate was coffee and junk. I started feeling like crap
When I started back it was just my favorite music and 3/4 miles walks for a couple of weeks then I started weight training. I didn't really get back to my high intensity stuff for a couple of months. I just started off slow gentle no stress fun cardio and weights. I didn't have any goals I just wanted to put me first after taking care of parents, 2 kids and a pouty pissed off dh.
So there is my no specific advise just find your happy to healthy.
