The first mistake you made was agreeing to be part of this scheme, the second was posting incriminating information on a public site. You should stop posting and retain a criminal defense attorney who will take steps necessary to protect you.
Generally, one should not admit to her crimes on the internet. The internet is not anonymous so statements made against one's interest can come back to haunt.
Generally, one cannot enter a conspiracy to defraud a bank and then when the conspiracy fails claim "I didn't do it/my co-conspirators did."
You should get an attorney. Now.

In PA a conspiracy is defined as an agreement between two or among three or more people to commit a crime and one of the conspirators takes a step towards commission of the crime (overt act). From the facts you describe you should quit posting about this matter, and you should speak to no one except an experienced criminal defense attorney. With luck you may be able to resolve this without criminal charges, or if you are charged, through a dismissal upon satisfaction or agreement, or a diversionary program.Good luck.
