Sunday morning can not go to church

Well going to church is not an option for me today.  If I could only get off the oxygen and walk I would be happy. I went to my sons house yesterday and that was very nice.  He bbq'ed and the food was good.  I had to leave when my tank was running out of o2. I know they tell me everyone is different, I am tired of hearing that.  I just wish I could know when I will start feeling better.  If I only did not have that surgery I would not be In this mess.Please dear Lord, make me better.......................
