Revision nose surgery...

I had nose surgery when I was 20. I didn't want it to be high like a celebrity's, I just wanted a natural-looking bridge like an ordinary(?) person's nose bridge.. Because of the nature of my school major, I take a lot of photos, and that's how I found out that my nose bridge was severely deviated to the right. Shocked, I went to the hospital when I was 22. They said I needed revision surgery, so I had revision surgery. Before even a month had passed, I had to go back to the hospital. By the time almost a month has passed, the bridge should not move and should be settled in place, but it was shaking this way and that When I went to the hospital, they apologized, saying they were sorry for making a mistake that only an amateur would make, and said I needed surgery again.. The thought of doing that terrible thing again sent chills down my spine, but the condition was serious enough that I couldn't avoid it, so I had the surgery. And now I'm 23... This time, the cartilage at the nasal tip is bent to the left, to the point that there is space on the right side of the nasal tip. The hospital is telling me to have surgery again. I'm not sure exactly whether it's ear cartilage or fat, but they say they need to cover the nasal tip with that? They said that would also prevent the nasal tip from turning white, but the nasal tip will become blunt and lower... When I ask why this happened.. they answer that they don't know either. I want to have the surgery done at another hospital entirely, but I don't have the financial means, and because I had surgery twice during school breaks, I even had to take a leave of absence... I really have no idea what to do,,, Will it go well this time.. I have so many worries... Please give me your opinions...
