I work full time too. Monday-Thursday are 9 hr days, work Fridays are 8 hrs, every other Friday off. I don't have kids at home, but my FIL lives with us. I do not have a sewing room. I either work on the dining table or crammed in between my bed and the closet. I don't get much time to sew during the week. I'm with you on the being tired afraid to screw up. If I sew during the week, it's the no brainer stuff like chain piecing pieces I've already cut. I save the cutting and any complicated piecing for my days off. It's less frustrating that way! :)
