Is my skin condition today for real...? (Is it because of the weather?)

I woke up this morning and looked in the mirror, and I was really shocked... ㅠㅠ
I haven't been getting much sleep lately, but why does my skin look so dry and dull today?
My makeup isn't applying as well as usual and feels cakey, so I'm upset... *sob*
I guess I should have put on a face mask before going to bed yesterday.
I'm not sure if it's because the weather suddenly got dry, or if it's just my condition.
How is everyone's skin today?
Are there any of you out there worried because your makeup just isn't applying today, like me? ㅠㅠ
If you have a secret, please share it!
