I know what you mean by hiding behind a mask. I do that too. Can't tell ppl how I really feel inside. Lie and say "I'm ok" when I really feel terrible. Sometimes if I don't have work that day I will skip the daily shower too but if I'm feeling depressed and bad I find it usually makes me feel at least a lil' bit better to take a shower. Feels like one small accomplishment for the day; sometimes doing small everday stuff and seeing it as one small, even though it may be very small, accomplishment helps with the depression.
