I went to bed very late last night and when I woke up I realized I was depressed or just tired all the time
Are you certain depression is the cause?
I don't think it is depression. I just had bad sleep.
Well, regardless of the cause I'm glad you're doing better. It's good that you identified what was wrong. Try and get more sleep for yourself.
But I like to stay up and play videogames.
You cannot sacrifice your health to play videogames. Sometimes you are just not going to have time to play, and that is fine. Your health is more important.
