How Can Impaired Motor Skills While Suffering From Potassium Deficiency Be Treated?

Hi, recently I was hospitalized for potassium undernourishment. I spent 3 days on a potassium IV drip, however, my body did not respond. I was given a prescription of potassium and sent home. My potassium never stabilized and less than a month after my hospital discharge, I was back in bed feeling like I was in the fight for my life. This time, my motor skills became alarming after this second episode ; I have to remember how to walk, actually tell my feet where to go and even then I still feel wobbly and weak . My hand writing now resembles that of an 80-yr-old (no offense to the elderly). Did I/am I succumbing to some type of brain damage? What do I do? Who do I see or talk to?
