My mother in law is in her late seventy s and very healthy and independent until this past summer .She developed a sinus infection- cellulitis which took a very long time to treat. HER doctors say she is fine now but something has happened to her. She has given up on life, cannot walk any distance (she walked at least a mile every day, mowed her lawn and traveled a lot), very sensitive to hot and cold, has lost weight (normal weight 120 lbs down to 107).She is confused and very depressed and has put herself in a assisted living facility. The doctors cannot find anything wrong but she insist there is a medical problem. I do not feel that this is depression, she enjoyed living so very much and always keep busy. Can you enlighten me on what you think may have happened to her.Thank you so very much.Joy H. Parrishvery sensitive
