breast cancer

Single, age 68 (very young), not in a relationship, but interested, hysterectomy at age 44, on estrogen replacement for over 20 years till last year, testosterone cream (a little) for 2-3 years till last year, surprise invasive breast cancer last year, lumpectomy Nov., as of April on Arimidex aromatase inhibitor, supposedly for next 5 yrs., I am trying to work the mind over matter, around the deprivation of all my "fountain of youth" hormones and am starting to despair over lack of physical both skin/touch and vaginal feeling and capability to respond to fantasy and masturbation (I try to keep up the good work and not let go of hope).
