How To Get Rid Of Dry Skin, Hair Fall And Tiredness?

Hello Dr. Grief.
I am a menopausal woman of 53 who does not take HRC. Daily, I take vitamin B12, D, Calcium (2K mg and 10K 1/wk),and a cod liver oil capsule. I am always tired, my skin is extremely dry, my hair is falling out, my moods border on happiness to depression and lethargy and I crave/eat sweets. What on earth can I do to combat this state? I am trepidatious about taking medication.
Any suggestions would be greatly appreciated.
Sincerely,
GF
