Obviously, I have not been sleeping well but I am extremely tired. I have tried taking melatonin but only slept a few hours. I can't seem to keep my eyes open at work. Is this just exhaustion or depression? Any suggestions for getting through this awful tiredness? I feel like a zombie and can't concentrate. All I think about is how bad I want to just lay down but then I can't sleep if I do. Thanks for helping me though this. Missing him more and more everyday.
