I just quit

I swear I do not know what it's going to be tomorrow, if I'm going to have the strength to get up when I wake up.
I'm tired of fighting. When they ask if everything is okay, I say it is.
Apart from that it's 4:00 in the morning and the demons in my mind have not stopped screaming.
Is everything alright?
Yes, I already said that it is because hiding behind a smile, has always been much easier than explaining.
