I have felt like this a few times but for a different reason (some other area of my life being neglected due to my quiling time) --- I recommend taking a look at what you do like about quilting and then deciding... of course after you finish what your working on and a then I would take a little break before making any decisions... but if you are frustrated and not enjoying the process or the end result is not worth the frustration maybe try something else for a while and then go back and see.
