I really feel your struggle Jeremy! I think we all do.
I think the only thing I can add to this conversation is just echoing what someone already mentioned about YouTube. It feels like the most stable and least volatile place online. If you have the capacity (which I know is a tall order anyway) I think it's worth giving some thought into starting a channel.
Like everyone else here, I have that same dysfunctional relationship with it and I hate the things I'm saying right now, but I don't think it's a good idea to not be posting your work somewhere in some fashion. Here's why:
When I really love an illustrator the first thing I do after following them is a complete deep dive into all the work that they've posted.
If I'm a super fan of that person, I'll follow them on almost every platform (IG, Pinterest, YouTube) and when I'm feeling stuck or I feel like I want to connect with another creator who I like or admire or just want to absorb their energy, I'll go to watch their stuff (images, videos, blog posts, etc).
BUT, if you're that person who I'm a super fan of, none of that happens if you don't have a back catalog of work in several places online.
That said, I'm very much so not an expert, so definitely take what I say with a grain of salt
but those are some of my takeaways.
