I Have Been Losing My Hair By The Handfuls, Every

I have been losing my hair by the handfuls, every time I brush it the brush is full, also all of my bottom teeth
have broken off in pieces (have full upper denture) and fallen out or are still broken and in the mouth and3 getting looser every day. (am trying to get into the dentist). Also my fingernails and toenails have these grooves running up and down the top of the nails, I have had (for the first time in my 67 years) 3 warts show up on my hands (both); My feet always feel cold and the other night I went to put a pair of socks on and before I did I thought I'd rub them to warm them up and the toes were all white and the feet were actually nice and warm to the touch and it felt like the insides were where they were cold and then I noticed that the soles were blue and the skin was moist and rubbing off. My eye sight has gotten really bad and blurry. Except for the teeth which has been a little longer, this has all taken place within the last 2-3 months.
