I am so sorry for the situation.  Please go and speak with an attorney in your area.  You have not given any time frmaes here as to when you reached majority, etc., which may be pertinent to the issue of statute of limitations.  Now, a minor can not legally enter in to a contract (that is what you did: contract your rights away) and there is also the issue of misrepresenentation or undue influence here. Get help.  Good luck.
