I just wanted to add, since you mentioned that you are now pale. That sufficient daily sun exposure helped me a lot during my recovery. You might have a Vitamin D deficiency if you spend all day indoors. Contrary to popular belief the sun can actually prevent more cancer than it causes and also plays a vital role in mental health. I sleep better and feel better with my daily sun exposure.
