yea it's hard. I mean there was a time where I loved my comic and I still do to some degree. but somedays. when i have spent about 2 hours working on a page i feel so disgusted. and i ask myself why? some days, I laterally have to force myself to finish a page. i realized that maybe i need to take a break, so i did then in the middle of taking a break i started another comic, binged in it for like three weeks and suddenly one day, i got disgusted again. so what's the point of this story? well it will happen more often than you think. no matter how much you love that project one day you will wake up and say, ugh fuck this. my recommendation is, take a break. walk away, give yourself time to miss your work, take a hiatus if you need to. then come back and see if you feel the same way. and just like @theperapen said, review it, give yourself some time before you publish it. that helps too.
so back to me, what did I do about the comic that disgusted me? well, I no longer feel that way. sometimes when you are mentally exhausted you don't realize it and it comes in form of disgust, unsatisfaction, resentment for your work and characters, and to be honest, sometimes, you may just have to ditch the work and your characters and go for a new fresh idea, there is nothing absolutely wrong with that. I've done it many times and I do not regret it.
That's my two cents hope it helps.
