I feel like such a f****** failure. I have been having trouble sleeping for the past two months and am in a constant mental fog. As a result I’ve hardly done more than four or five hours of work a day as a graduate student. I have so many people supporting me and so much funding and I feel like I am letting everyone down and not living up to what I should be. I should try harder and be better but I’m so tired and can’t focus and just can’t keep normal working hours. I feel like a whiny p************. I should just s*** it up and deal with it. Everyone is tired. I hate myself for this.
