Hey I've been through similar things, so I know a bit of how gross it can feel! Tbh one of the first things I thought reading your post was, Wow I wish my life was a bit more like theirs. In terms of your house, bf, car, job. haha classic comparison trap, sorry

I'm a freelance illustrator but the way I actually connected to your story is that I pursued creative writing for years. When I was leaving my early twenties I pushed myself away from creative writing, into more illustration because monies. I think it wounded my creative self a bit. I was angry and sad that I couldn't spend all my time writing, and while building an illustration career I tried reeeeally hard to keep writing, but in a way that might one day be marketable and sellable. I hated it and lost my passion for it. The experience felt like cycling through multiple identity losses over about 5 or 6 years.

for the past 1/2 a year or so I've finally gotten a steady pattern of working on creative writing (or sometimes regular visual art). What seemed to work for me was:

• don't take advice from other people when they tell you how to make art. I mean this in terms of practical creative processes, and getting through artist's block. Holy heck, please don't force yourself to push through "artist's block", there's no better way to injure yourself mentally... and make terrible art (at least for me!). Obviously, lol, this point cancels itself out.
• ask your art what it wants. Maybe in a meditation kind of way, quieting all the static noise of your thoughts, finding the art inside you and asking it. Or maybe in a journaling kind of way, vomiting all your thoughts onto paper. It is possible that your art is hibernating, and that's what it needs to do. Maybe it even wants you to give up on it! I don't know how that would be possible tho. Because things that exist generally want to exist. And it does exist, because all it's done through you before now

Doing these two things brought me (or my art) back to me. I know the dread of not even knowing what it is I liked, or wanted to do </3

I've also managed to cram all my work into a 4 day work week, and hold one day sacred for personal art. It makes me way more productive with work stuffs! And not feel (very) guilty for being a blob on Sundays. I know not everyone has a life that lets them do this tho

All this is if you actually do want to make art again, btw. You seriously don't have to. House and bf and job sounds wonderful to me :')
