oh yeah, that sounds a lot like a burnout. defo take a break, my dude. when you start talking about finding a purpose you know you just need to rest, and find the pressure youre putting on yourself and remove it
although,
what about no paper? no pencil or tablet? get like, a leaf, yeah, and some ink / paint, and just go hogwild on any surface you like. do some grave rubbings. do some face painting. get so far separated from what you consider drawing that it loses that negative feeling, and youre just playing with shape and colour and texture. you might find something - a method of painting or printmaking - that you can take into drawing to just make shit so much easier, or you might find that you prefer making leaf splats and do that forever. or it might just be a good release of energy.
the reason i recommend doing low stakes, not-drawing stuff like this is it takes all the pressure and self-criticism off. you cant be like 'aw man, i really splatted that leaf wrong, im awful.' 'i really painted half my face pink super shoddily, i should just quit' - theres no standards, no rules, and no stakes. it can be pretty freeing, and dislodge that fear or expectation youre holding over yourself that is putting you off drawing.
this feeling might also be because you just quit your last comic - it sounds like youre in freefall between projects. like, personally, i only ever draw for my comic/s (or studies for practice); i can never, ever see the point of standalone drawings or fanart. so when i dont have smth to work on, i feel pretty directionless - its only when i have a new Thing to develop that i start working again.
but yeah first things first: take a sodding break
