Does anyone have their aging parent on Zoloft?

My 96 year old mom can cry easily. She gets tearful because she can not do what she use to do when she was younger and feels weaker. Her mind is pretty good, just forgetful on daily events. She is well aware her days are numbered. She only takes thyroid medication, vitamins, and melatonin. I am just wondering if Zoloft could help her feel better and decrease her mourning her younger years. Thanks everyone.

P.S. I'm taking Zoloft the last month from having caregiver stress and anxiety myself, lol!
