It is true that we have to adjust our lives at times according to what we are able/capable of doing. I have been on both sides of that coin. A couple years ago my husband was doing treatments for lung cancer. When he had the radiation and chemotherapy we had to have our "fun" (as little as going for a short walk) around how he felt from the therapy and when it was. It is also very hard on the person who has to accommodate the other. If you don't have anyone depending on you, etc. it must be easier.
Now it is me who can't do anything in the morning. I ask my husband (who is a "morning" person to not make appointments in the morning whenever possible. He goes to the VA and sometimes does not have a choice. He can go alone to most of them but he likes to go along - it is 30 miles. Then the plumber called to fix a toilet and of course he said come about 9 a.m. I try not to get mad, etc. but know he just does not understand!! Do the best you can - learn when is good time to do things and when you just can't. Those around you may never understand but truly your happiness is the most important!!
