Unfortunately, you will not be able to get an answer to problem until you hire an experienced Family Law attorney to review all of the court documents and to determine what steps can be taken. You should do that immediately.
You should not attempt to do this without an attorney. However, if properly done, with the cooperation and agreement of all 3 parties, you can pull this off. You should end up with a new birth certificate showing the biological father on it, with his last name. There are two legal actions that must be filed, and you should retain an experienced Family Law Attorney.
Signing a voluntary surrender of parental rights for the purpose of allowing a step parent adoption does not relieve him of past due child support obligations. However, the surrender is only good for 6 months, and you must file the adoption petition before it expires.

I think that you should get some social counseling because this is not a legal question so much as it is a personal decision for you. Legally, you can do whatever you choose to do. No one is going to make that decision for you, and they probably cannot do anything at all without your consent. But, it may be a decision that you live to regret, because it is not easily, if at all, reversed. You may never see your daughter again. You say that your parents "want" to move to Mexico. You should...
It is not considered an appeal. However, you have the right to pursue a legitimation action of your own. The petition would name both the mother and the legal father (the one with the prior legitimation order) as defendants. Do not try this without an attorney.
