My suggestion would be to tell your family that you love them, but you need a half hour (or however long you think would be good) when you first get home from work to unwind and that after that half hour, you will be available to them. "Mom's half hour" or whatever you want to call it. It's a way of setting a boundary for yourself and it's what you want and need. Your family can wait and all will be well. And, in fact, you will be more receptive and more responsive to them when you are feeling more relaxed after having your time and space.

Would that sound like something you would enjoy going home to?
