Short and sweet answer: You should see a board certified plastic surgeon in your area to discuss treatment options.
Long-winded: Without going into too much detail, you could benefit from an open rhinoplasty to help address your concerns regarding the width of your nose and your nasal tip. You could benefit from cartilage grafts, lateral osteotomies, alar wedge excision, alar rim grafts/lateral strut grafts, and tip work/sutures. A board certified plastic surgeon in your area can discuss your goals and suggest solutions to your specified goals in person.
