I’ve noticed that whenever I’m sleep deprived, I almost always become very depressed to the point of having suicidal ideation. If I wake up tired in the morning. It’s almost guaranteed that my entire day will be ruined because I’ll be too much of a mess to be able to do anything or go anywhere. 

Why can I go from feeling completely normal one day, then wanting to die the next day? How can I combat this besides getting more sleep? Are there any vitamins that could somehow help?
