Nikki,
If the stress level is too much, think about hiring a real estate attorney. Before doing so, ask about his/her fee. It shouldn't be more than $200-$300. They will explain everything you don't understand.
Many may reply and say that you should have your broker explain it but unless you have a buyer's agent, your broker doesn't really work for you. Most of the time (look through those papers) you have to sign a dual agent disclosure statement that states your agent doesn't really work only for you.
