When you work a full time job, have a long commute to and from work, have another full time job at home you are tired by the time you get finished with supper and clean up! Please give yourself a break; you have a lot on your plate right now and perhaps you could take one evening or one weekend day/evening for your quilting projects.
Some days when I get home all I want to do is get my shower, sit down and don't move! My DH is good about preparing supper for me and Gson, but does little housework, he does wash up after supper. Some days I have more energy than others and can get a few seams sewn, some days I have no energy left and don't get much of anything done.
Don't beat yourself up, just choose when you feel like you have 30 minutes or more to dedicate to your hobby.
Best of luck! delma
