Sorry to hear about your troubles. I'm glad your health has improved, but sorry to hear about the depression. I wish I knew what to do about that.
A couple of months ago, my wife and I started walking. Just for the heck of it. At 53, and living a rather sedentary lifestyle, I decided it was time to get the heart pumping. So I adopted the slogan, "Make My Heart Great Again." I pray that it's working. I'll pray for you too.
