Sorry to hear that you haven’t been feeling well, and well done for getting on the road to feeling better!
I think that something that is helpful (though hard to do) is to keep in mind that the critique is of your work, not your person. Someone not loving what you have made doesn’t mean they don’t love/like/respect you. (And actually, someone not liking/loving/respecting you doesn’t mean that you are unworthy of being liked/loved/respected!)
Also, I think that the thing that’s helped me the most is to get a really clear understanding of my intentions when I make something, and also when I ask for feedback. Say for instance I want to make something that is fun for me to make, and doesn’t take very long, but does allow me to practice panelling (which, coincidentally, is what the comic I’m making is :L), if someone then comes and tells me ‘the layout isn’t very good and the story isn’t interesting to me.’ Then I’m like... okay, that’s fine because the point of this comic is for me to get better at layouts as I go along, and I wasn’t trying to please that person with the story anyway, I’m just trying to make a story that makes sense!
If someone gives you specific feedback about a specific area that you were curious about (like for instance if you asked someone ‘why is this layout not aesthetically pleasing?’), and they give you feedback that’s actually helpful like ‘it’s off because you haven’t split it up in a ratio that feels balanced’ then its all good because you can take that and learn from it. You don’t have to agree with it, but it might help you to identify what you actually think is wrong and fix it in the way that works for you. But if they give feedback that is just mean like ‘it sucks because you suck!!’ Then that’s not helpful, and might feel bad if it’s someone whose opinion you care about, but it’s also not something you even remotely have to listen to! (But also, why do you care about the opinion of someone who would talk to you like that? You don’t have to! You can just not care about them, if they are gonna be so horrible, it’s okay!)
Basically, the only critique you have to listen to is stuff that helps you to achieve what you set out to achieve. Not everyone will understand your vision, but people who do will be able to offer helpful critique. And you might be able to find some use in the critique of those who don’t. Just try to let it wash over you and don’t hang on to any of it too tightly, because what helps you will stick with you anyway, and what doesn’t is not worth keeping.
