Depression?

I've had depression before back when I was 14-18. It started to get better whenever I realized the feeling and I tried to counteract it by doing things I loved. 
Well now I'm 21 and I have a lot of responsibilities and a lot of things going on and I have been so stressed that I don't even have a sex drive. I don't even have the energy to do regular housework all week. I literally work 8 hours a day and come home and just relax until 8 and I am already finding myself in bed. I can sleep 11 hours and I feel like it isn't enough. 
I did labs and they all came back normal. I was afraid I was anemic or my thyroid levels were off. But everything came back fine.
I get easily stressed and irritated and I find that I need a lot more time alone to cool off. Does this sound like depression? Because when I was younger my entire body would hurt and feel numb at the same time. I'd cry a lot and I'd also feel useless. I don't feel that way now. I just feel super exhausted and I don't find myself wanting to do the things I used to.
