Still standing

While I did indeed have a long nap, I managed to stay standing today.  I know that does not count as exercise, but it seemed like it.  I just feel like going through the motions and give up.  I don't want to wait for someone else to help me.  I want to do so myself.  However, I have no idea where to begin.  I am a diabetic who has suffered back pain and other issues.  I guess walking would be the best option.
