No don't give up--just put it aside for a time. Try something else--like sewing yourself a nice new summer tote or maybe some cross stitching. Then when you just can't stand it anymore, go back to quilting. I just love to sew, so I sew different things and make things for others. Then its fun--not strenuous or stressful. I am glad you have two new machines so I am sure you can do a lot with them--try your fance stitches. You will be alright I am sure after you have some time off from quilting.
