can i get my daughter back if i was strong armed into signing my rights over

It might be possible depending on how it was done.  It might be possible to appeal or set aside the order.  However, you have a very limited amount of time to try to undo any order that was entered by the court.  You should contact an attorney ASAP and schedule an appointment to meet with them.  Make sure that you have with you a copy of the order and any other documents that are related to terminating your parental rights.   (I suggest that you get a copy of the entire court file. ) Once the attorney reviews your documents they can tell you whether and how, you can get your parental rights back.  Please move fast with this because both of the remedies listed above are time-specific.
