4:26pm and I’m falling asleep

I’ve been like this all week , I’m so burnt out and I’m lacking iron so badly , I’m on my period too and I also had an horrible week last week mentally so all that crying and anxiety has taken all the life out of me. All I’ve been doing mainly is sleeping in heavy amounts , I was going to go out every day this week but I couldn’t manage it. I’ve been eating like an pig but I can’t get my energy up. I’ve been sleeping for over 16 hours an day and I still wake up exhausted. I’ve had the flu for 3 weeks now on top of everything I’ve just mentioned. I feel depressed because I can’t do what I want and need to do because of the lack of energy. I’ve had an back injury too. Someone please just kill me now
