I feel very down, and i don't know what to believe in or not... specially in fan-art world where a piece you can see as nice other can say it's wrong.
All i do is just not enough, i try to be my best self but all i end doing is being a failure; nothing i do is good or gets what it deserves... except when i do something wrong, then everyone goes to jump and point those failures constantly. I had plans of doing a thing for June 21st but now i don't even want to see a paper, pencil or anything related for a time because i feel like trash in a world that is not made for me.
So... yeah, i'll go to the corner and cry a bit for a few weeks or months; because it's all i deserve for now.

I feel you. This is exactly what happened to me on my old account. No matter how much I could work on my art, I never got constructive criticism, only hate comments and PMs and most of my votes were cyberbullies constantly v0ting my work. When I spoke up about the harassment, all the popular artists found to do was to call me a "retard" and an "attention beggar". This just killed my passion for art and I deleted all my drawings after multiple panic attacks.
Unfortunately the art community isn't really supportive and doesn't try to help other artists to feel confident about their art and to improve. It is more about feeling superior to other artists just because of a number behind 'followers'. At least it was the experience I had with the Art Portal.
I didn't interact with the Art forum lately but I think you can ask for reviews and tips in a thread. From my experience, people there are more serious about art and don't try to belittle other artists like in the comments. I feel like I started to improve since an artist recommended me some quality art teachings and motivations. After, it's up to you to choose what you want to do to feel more comfortable with art. Remember to take breaks sometimes, it actually helps and you will notice improvement more easily than if you were working 24h/24.

It's been something i've been carrying for years, and now i finally exploded those bad feelings out of me. I had a DeviantArt before starting to upload my work here and all i felt was emptyness and after years i rememered i had this and i started uploading here to see if i could get some feedback... sadly is not tha way.
I follow many that draw great and some do have characters that look one thing but they aren't and it's confusing (i won't dive into this too much) but they do get comments and feedback and the ones that try to rise by improvement just are ignored or called as you said "Attention beggars" when what they want is grow and improve.
