Hi Austin and Welcome to HealingWell!
It is true that wanting to stay in bed and having very little energy is associated with depression but that could be associated with so many other things as well. If there is a decreased red cell count in your blood, that can cause tiredness and lathergy, as can decreased liver function. The best thing is to see a doctor and ask him to do some bloodwork to see if there is a physiological cause. In particular your red cell count (FBC) and liver function (LFT).
I hope this helps
