HELP! Stressing over severely chapped lips! TT_TT?

I don't even know how this began but it's been a little over a week and it's gradually getting worse. My lips are chapped to the point where my lips are no longer flaky-chapped but the scars are so small that it's even darkened the color of my lips and it's spreading to the corners of my mouth. I'm so worried it's going to permanently darken my lips! At first I used the tooth brush method and it made it worse. I did it again and it got even more worse. I left it alone and it didn't go away. I've used Yes to Carrots--CRAP. Vaseline--CRAP. Aquaphor--CRAP. So my last resort is Burt's Bees and I've been drinking a ton of water. I wish this would go away! I've tried covering it up with red lipstick but the tiny scars show through and it's disgusting. Help.
