I agree with others that I would not trash this quilt. I see nothing wrong with your quilting and as others have said finish and either use it as a car/garden/picnic quilt or donate it (it will be well loved). I am in the process of quilting a top and I began in the center and worked my way to the edges and alternated direction of stitching with each section of blocks so that may work for you. In the end I would finish the quilt and then wash and see if it a keeper or a donation.
