Man, some would kill for your talent. Don't worry, a lot of artists feel the same way you do sometimes. Maybe you could try new things?

Two possible reasons.

1: You're too much of a perfectionist.
2: You've hit a plateau.

You actually took the words RIGHT out of my mouth. +1

Poor guy. :< I know the feeling well. Sometimes it feels like you're not drawing what you see in your head.

That just means you're improving though! You can see all the mistakes you're making and with a little practice, you can start to fix them more easily. It means you should keep drawing, more and more, and soon your skill will match your vision!

It also couldn't hurt to start looking for various tutorials in the areas that you're having the most trouble with! Or even just taking a close, critical look at art that you like a lot.

I'm kind of in the same situation at this very moment, you know... I know how this feels. You're my favorite artist, would be a shame to see you stop...

I've got the same opinion as the other above.

Sorry to hear that :(

Maybe try a different style or using a different medium. A change of pace might do you some good!

Remember the special feeling of fun from your first drawings!

Perhaps you are forgetting the fun! ♪

その気持ちがよく分かる（自分の絵について）...それでも、描くのが下手だと言うわけではないよね。いつか本当に風人さんのように上手になりたい！こうなったら残念だね...もうすぐ絵を描くことが楽しくなるといいね。

It's a perfectly normal part of being an artist, or doing anything creative.

Your ability to critique art and your ability to create art often surpass eachother.
So there are times in the cycle where you aren't happy with your art, but that doesn't mean you are getting worse.

It was a nice almost decade of diligent following across several art sites, I guess...

I know you can't understand me well enough because I'm a worthless english viewer and fan but please don't go breaking any hearts over this natural cycle of being an artist.
