I understand if you're leaving, but don't be so rude.

To put it in simple, polite terms, you're leaving because you feel unnoticed and you want the attention that other people are getting more of in your eyes.
That's not a wrong way to feel; most people on ANY drawing site feek that way.
However, if you felt that way all this time, did you mention it at all to your friends here?
If you had, and people still ignored it, then you're right to be upset...
But if you never once mentioned it to anyone here that you felt ignored, then we've got a problem.
Everyone here, including you, have ignored someone unintentionally. You just need to remind people. I've done it before, and so have many creators. I think TCG's done it a couple of times, and recently.

What I'm trying to say is that, well, maybe you should mention your feelings to friends earlier on, especially when they're affecting your experience on Colours, and even if it happens on DeviantArt.

But if you're still upset beyond consolence, then I wish you luck in DeviantArt.

^I agree
I actually dont really care much for follows or likes I draw because its what I love to do and sure its nice to get a comment every now and then but it doesnt matter too much to me

D:

Look at me! I have less fans and attention, and I'm still going! Honestly Dot, your art is fantastic and amazingafying. Its fine if you're leaving.
At least you're leaving still remembered.
