Revision rhinoplasty is complicated, especially for the kind of problems you describe. I do get a sense of the asymmetry and the collapse of your nose from your photos. Before pictures and better pictures of your nose now would help more but what you really need is an expert rhinoplasty surgeon to examine you and give you an honest opinion. Most likely you will need septal cartilage to give you better tip support and improve shape. You may need additional cartilage as an lateral alar strut to improve alar shape and spreader grafts for the dorsum of your nose. The nose has a very complicated anatomy and now more complicated because of the operation you've had. Good luck!
