I'm sorry. I'll keep you in my prayers.
I'm an older person too with a host of similiar health issues.. It scares you...dealing with unknown problems...but your doing the right thing; You follow what the Doctor wants you to do, study the "health issue" as best you can and pray. I see your faith is strong.
I'm sorta new here...but I see your "cyber handle" and it makes me think of all those old "Autumn jazz standards" I love so much. Gets me singing.
That's cool huh? You put a song in my soul!
Everyone has something to give here...please don't 'belittle" yourself. Look at "George Baily's example"...again this season. Timeless.
Take care...m.b.
