Do you ever reach a point where the days just all seem to blend together?

I’m not having a bad day or anything like that but I’m absolutely exhausted. I actually had to check my phone to confirm what day it is. Yeah, I’m just that tired. 

I feel like I could sleep for a lifetime and still not be able to makeup for all the sleep that I’ve missed recently. 

Anyway, I just wondered if anyone else ever reaches this point?
