It is always hard to say, just because you present with similar physical features does not necessarily mean that you have Marfan's. There are various support groups that might be able to help you and you could go to your local health department or health clinic. The health department can sometimes help with getting medical coverage or finding physicians that offer sliding scale payments (meaning they look at your income and find a payment scale that you can afford).
