i dunno, i think i tend to find that what im doing is growing a story from a seed that was planted when i was having a hard time, but can only grow into something of substance when im stable. so while im drawing on my own traumatic experiences - from very specific ones to universal hardships - i can only do so once ive got a bit of distance from them
for example, theres a comic i will make one day about a really traumatic 6 months in my teens - but im not gonna actually start working on it until ive had like, a lot of therapy. bc turning your trauma into narratives for the consumption of strangers means not only drudging up a lot of deeply emotional stuff, but also finding a way to repackage it to sell. its very vulnerable.
that said, i think often storytelling can be used to process trauma - in fun home or maus i think theres certainly an element of the authors processing the losses of their fathers and wider cultural traumas in the production, which can be seen particularly in the start of part 2 of maus.
that said, theres a lot of stuff i make that has little or nothing to do with my own experiences, and comes from a place of creative curiosity - i think its really important to have that stuff if you do make work about your own experiences, bc you need a break from that weight.
