here too it's over 4 am Now 4:48am In some minutes I'm going to start another day but haven't slept evn for an hour yet I'm so sorry But your schedule seems to be really tough I've experienced sleeping deeply for sometime is still better than not being able to sleep or just falling in bed for hours so play some soothing music and sleep then wake up have good amount of water, a big breakfast and at job just stay calm It must be so tiring for you So I pray and hope you'll get an off soon today Have a nice day 🙇♀️
