I'm 51 as well, divorced, and I have bipolar disorder, essential tremor, Meniere's disease, asthma, and Chronic Regional Pain Syndrome (CRPS). Most of these conditions are hereditary, except for the asthma and CRPS.
Right now the biggest problem is with bipolar. It's taken quite some time for me to become stabilized on meds, but now I take 3 different ones and I think between my psychologist and psychiatrist we're on the right track. I still have my manic and depressive episodes, but it seems like they're getting farther apart.
CRPS was a result of a broken foot and two surgeries. I've had 5 pain injections and been on several different pain drugs, none of which worked, so the only recourse I have for pain control is with a neurostimulator. It's implanted in my back and works like a TENS unit, only it's internal not external. It provides the same type of stimulation.
Even with all this stuff, I refuse to let it run my life. I'm a stubborn woman! I'll continue to do what I need to and I'll enjoy it too!
