Olga, personal injury law is something I can only give you general information upon here. Your claim against the insurance company is all about how much money you can reasonably prove that your injury cost you, after you show that the the defendant was negligent or somehow responsible for your injury.
If your lawsuit looks like it would be successful, you will usually be able to negotiate a settlement and recover money to compensate for general pain and suffering, loss of income, expenses like as prescriptions and travelling to and from your doctor, and for future loss of your income.
The amount of compensation you can receive will depend on how serious your injury is and how it has affected your life. The court will often take into account your age, whether you have any pre-existing injuries or conditions, and whether you somehow contributed to your own injury.
There are tight timelines for filing a claim. You mention that it was on private property, but I'm just making sure. If it was on municipally or federally owned property then go see a lawyer right away.
You should go see a personal injury lawyer as soon as possible. They advertise heavily so you won't need a referral. Many will charge you nothing until there's a settlement, and will be able to put you in touch with doctors and other professionals you might need for a complete diagnosis, which will be necessary for you claim.
It's difficult to give you an estimate of what you might earn. If you're a professional race car driver or dancer your claim for a broken ankle is much different than if you're retired.
Good luck Olga. Don't delay on seeing a lawyer.
