Saying "No" gets easier the more you do it. You'll also feel less guilty the more you say "No." Before I was in nursing school I was a stay at home mom for many years. People expected A LOT of me. They were used to me always doing this or that for my children and family. Initially I felt very guilty for not attending parties or baking goodies. However, I got really good at saying "No" and felt better about it too. You will too. You spent all that money on a machine for you and to do what you want, not what others want you to do!!! Good luck, you will learn not to feel guilty and to not let others make you feel guilty. If nothing else, feel free to point out to them that it's NOT nice of them to try to make you feel guilty. It's very selfish of them actually. Tell them there are plenty others who will make that for them if they wish.
