Congrats on 6 lbs....that is awesome! As for walking, that is just one form of cardio. If you are doing other things for exercise there is no reason you have to be a walker. If you don't enjoy it, then you are right to find other things to do. There is no rule that you have to walk to lose weight, it's just what a lot of people choose because it requires no equipment and is a simple thing to get into, or a number of other reasons. I rarely walk myself, but I do lots of other things for exercise.
Scale addiction...I have it as well and it motivates me. For others it is more of a problem and they try to avoid it, but it's a tool for me. As long as it is not hurting your mindset in any way you will be okay...just know that some weeks you will have a little gain or lose nothing, and if that messes with your head then you might need to cut it back.
