I have noticed that I've become extremely apathetic to things. I have trouble discerning between happiness and sadness; it is almost as if I have lost the ability to feel. Events that often evoked emotions in me before (ex. parties, funerals, etc.) all seem like "nothing" to me now. I even lost the feeling for hunger, yet I can still eat normally but for some reason I do not feel full or satisfied. I would like think my sudden change in mental state is due to my high stress environment, but at this point I'm not sure anymore. Should I seek professional help?
