Hello there Carlos,
I have been reading the conversation and I think I have been in a similar place once. Not that I am comparing something. That is not truly what I am trying to do.
I can only speak for my experience...
In my case, I think I felt the same as you do, and, sometimes I still do. There are days when I think my art will always be ignored.
But, I came to terms with there is nothing that I can do about it. The feeling will not go away even if I get all the subs and likes on tappas and webtoon combined.
The feeling is more... like a black hole. It will never never go away, so what can I do with it?
Well, in my case, I learned to live with it. I stopped doing art for others, or trying to charm and wow them, and now I do it for me, and I try to improve for me. I know I will always make better in the next page, comic or illustration... I guess everything else comes natural...
I live comfortable knowing that I will try my best and there is nothing else that I can force to happen.
And something else, don't be shy to try to seek help. Professional help. It is not bad seeking help. seeking someone to talk to. I really think that seeking that help will make everything easier to cope with.
I really wish you the best.
Regards,
Daniel
