I work full-time and have three kids...I know it is hard to find the time in the day to sew. I go through sperts where I don't sew much and then I make up for it. Usually when it starts getting cold outside, I just want to stay inside and sew. I get the most sewing done in the winter. Summer...I just want to be outside(as long as it's not too hot, then I'd rather stay inside in the a.c.) and don't get as much done.
Maybe you just need to take a break from sewing(just not too long, you might forget how to do it :) )and go back to it when you are ready. Your fabric will always be waiting for you. 8-)
