I can relate to the fear that changing habits can also wreck one's creativity, depth of character etc. However, I have found the opposite to be true. Depression and anxiety have obscured creativity. I don't feel like myself because I feel heavy, dark, and paranoid when depressed and anxious. I think it makes it harder to focus and so altogether I am not my best self. I welcome throwing off the crusty negativity that seems to bind me up. I want to feel raw, refreshed, and new. Personality and creative gifts won't go away, I don't think. Anxiety and depression are like veils covering one's light.
