My mother in the last 6 months has lost more than 30 lbs. Her mobility has decreased significantly, and in the last 10 days, can not move around by herself, she shuffles when walking. She cries a lot. Sleeps all night, and most of the day. Recently has nausea a good part of the day and is barely eating. She has some difficulty swallowing and gags when drinking. My dad is her primary caregiver and is at his wits end what to do with/for her.
