First, your body isn't a laughing stock. Don't be so hard on yourself, you look amazing. I recommend starting hrt right away though if you want to keep that body, you're really, really feminine and getting on hrt will help to keep that (depending on genes ofc).
Second, you don't need rib removal surgery lmfao. People use that to become more flexible for autofellatio, it doesn't have a noticeable change in your outward appearance.
Third, your waist is already really thin, I take it you're European? There's so many people who'd die to have a body like yours, mostly women.
I hope this helps in some way, you're doing great! :3
