I agree with LTD...a simple meeting will no doubt cost you nothing (a lot of lawyers offer a free initial consultation, or one that's very affordable), and will give you an idea on what your options are.
I too have second guessed myself a lot in my life, and the way I "trick" myself into moving forward is to take little steps that do not force me to make any decisions, such as making a call, surfing online for more information, or speaking to a lawyer. I'll agonize over the actual decision later on, but at least I'll be well armed with the right information.
Just give it a shot and see where it leads you; it might be very surprising...
