You remind me of a friend of mine, she gets so anxious when she buys something for herself she really doesn't enjoy it. Enjoy your new sewing machine. As long as you can afford it, why worry so much? Have some fun with your new sewing machine. Not to be morbid, but, no one knows what the future holds. Live life to the fullest. I am now disabled and sewing is very painful for me, but, I have to keep going even though it hurts me physically. Relax and enjoy that you can use your sewing machine now, at some point that may not be the case. When that time comes, it is better to look back and truly enjoyed yourself. Sorry, don't mean to be a spout off, but when you are in my position, you learn to not sweat the small stuff!
