Don't feel any need to apologize, there's nothing wrong with wanting to start fresh. Especially given the circumstances. I'm kinda struggling to find the right words since so much has been said already, but I'll try. It's good to see you're still with us. I don't even know if you remember this, but that Q&A you did where answered my question about your backgrounds really opened my eyes. I've taken much of that advice to heart and it's been very influential to my art ever since. Especially the tip you gave about giving the character a gradient border and then gaussian blurring it to make them stand out against a busy background. I use that so much and I can't thank you enough for it.
And thank you for being so upfront about this in general. It takes so much bravery to be this open. Please take care of yourself, as hard as I know that can be sometimes. I can't say I've ever been in your exact circumstances, but I have felt similar feelings at least. I know how tough it can be to continue when you feel like things aren't ever gonna get better. They do, eventually. Life's never perfect forever, but it's not all bad forever either.
This is probably a small comfort at best, ultimately, but I still wanted to let you know the impact you've had and try to throw some support your way.
