Is it normal to be tired of living?

C
I'm just so done with life. (No I'm not suicidal) I just feel as though I don't want to live, I try being happy but I simply can't ? I try to overlook things and think positively but there's too much negativity. And once again, I'm not suicidal nor do I plan on killing myself lol. I just wanted to express how I feel often, I have completely lost interest in many things, and all I want to do is sleep. Are these signs of depression? Or am I just exhausted from all the stuff that happen to me lol?
