Modeling and pageantry, I can definitely see height being a limiting factor. Acting however, there are plenty of incredibly talented actresses who are shorter than you, so you can make it up with practice and skill if you're willing to do that. Fact of the matter is that
Hollywood wants taller men, so shorter women can sometimes be advantageous.
And if they're too short, they'll use camera magic.
There are a lot of questions to consider. Are you OK being away from your life as you know it now for at least six months? Can you tolerate pain, both physical and mental (from isolation, anxiety, panic)? If you're willing to go abroad, can you afford at least $25,000? If you're in the US and want to do it domestically, you'll have to prepare 3x as much -- none of this is covered by insurance.
And yes, you will most likely lose mobility and nimbleness. If dance is a big part of your identity, be prepared to make a trade without a return policy.
How old are you? A rough range is fine, I ask since aside from height is ageism in your industries of interest. I remember reading a story about a woman who endured CLL in Russia to bolster her modeling career, but aged out anyway. She was happy with the results regardless, but something to keep in mind for professions that place heavy weight on looks like modeling.
If you're considering CLL, do it because you want to be taller. Not specifically because you'll think it'll help with your career. Similar advice is given here to many men: don't do it because you'll be able to land more dates with women. Odds are yes, it'll probably improve. But it'll still be your old self attached to those longer legs after the first impression.
