Brittle fingernails symptoms and conditions

I am 68yr old female with neuropathy in both feet and it feels like it is traveling up my legs slowly. My fingers are very sensitive and sometimes they itch uncontrollably. My fingernails are brittle and hair loss has subsided since I cut my dosage of lipitor from 60 mg to 40mg. I was also on lisinopril - and quit it about 3 months ago. I have been reduced to a sitting zombie - not able to sleep at night and able to sit for 3 hours every day unable to move - am I doomed to this life because of lipitor?
