Kind of sounds like apathy what your describing and yes, that could be depression. I never cry. Yet I can get deeply depressed which can be like you described or in total despair and sorry. If you have not seen a doc you really should. There is absolutely no reason to be suffering this way. Even if you think you are not suffering, there is no reason you have to feel this way. There are many good meds that can relieve much of these symptoms! Depression is the easiest symptom to treat in my case. Next would be my anxiety. There are some issues that can not be treated for me, but every little bit helps!
