I agree Jill. Stress and poor diet certainly contributed to my anxiety and depression. Another factor for me was Vitamin D deficiency. After increasing my intake of Vitamin D from 1000 IU per day to 8000 IU per day I noticed I was much less angry, although not necessarily less sad. Life is still difficult and it is hard to be happy when bad things are happening, but since increasing my vitamin D supplement I feel much more able to cope with sadness.
