It's totally normal, and might be unavoidable. It seems like you're uploading your art not just to show your creative output, but to feel validation. You want to know that your art is good and well-liked, and that people enjoy that art just as much as they enjoy any other art online.
You could try to do something like only post your art to a website that you use as a portfolio where the numbers dont exist and you're not really competing with others on the same platform for visibility. That may not work if it's truly about validation, as you couldn't just put that away without needing to transplant the validation somewhere else in your life.
Your best option might be to try and more thoroughly engage with whatever community you already have in an effort to make the engagement that you already have feel enough. Maybe something like drawing requests of dumb ideas people have, just for fun, to get them commenting and have you draw something that's just for the viewers and not for a higher level of art and engagement.
Oh yeah, I was just saying that as a short hand. You'd want to pick and choose mechanics to bring over or modify, but OP specifically mentioned wanting to "slog around" implying heaviness or something more than cosmetic or survival necessity from wearing the suit, not that that's what everybody would want.
With OP's vision in mind you'd at least want the animations for equipping and unequipping the suit, heavier sound effects, leaving the suit behind by itself or in a rack or locker, extra carry weight, extra modification slots, the visually noticeable but unintrusive helmet overlay, maybe some others, but that gets close to what it seems like they want.
You'd want to balance it somehow so it's not always a positive to wear if it were some sort of special suit that wasn't required for zero atmosphere traversal, you could go the fusion core route like 4 or figure something else out.
