Honest question - did you give up counting, or give up finishing the comic at all?
She stopped creating these comics and fell off of the face of the internet for two years. She was eventually able to come back and share her experiences after getting professional treatment and taking prescription medication for some period of time.
Your post is along the same lines as many of the people shown in the piece (substitute philosophy for yoga while watching the sun rise, "I know exactly how you feel, but you should just <x>", etc.) It's also incredibly condescending to trivialize two years of debilitating clinical depression as a little bit of Sartre-deficiency because she was eventually able to come back after getting on psychoactive medication. I'm also not sure if you'e aware that feelings of meaninglessness and purposelessness are common in clinical depression.
Your other posts are even worse, as if depression is a gift (seriously?) to creative people so they can angst up a bit and play the tragic, misunderstood, tortured artist. Or even more callously, because it's entertaining for other people (my father was clinically depressed - it's not.)
Clearly you don't "empathize completely" and your suggestion that you've gone through "such crises" yourself is presumptuous and insulting, as if gripping with nihilism now and again makes you qualified to diagnose (and undiagnose!) mental disorders in other people - of course, if you have had to undergo prolonged therapy or take SSRI's daily, please do correct me. I'm assuming that you mean well, but your attitude is cavalier and you don't seem to have thought too much about anything you've said here.
