Attempting to do an appeal alone in this CPS matter is not the best way to proceed. You have rights but you have to act to protect your rights. Because this matter is so important you should really get a lawyer. You can miss and say the wrong things if you are not represented by an advocate as your attorney. The appeal record is very important so have an appeal attorney advise you.

You'll need an appellate attorney. Ask around and see if you can get one appointed or pro bono as part of some legal aid project. The time limit for filing an appeal is very short usually, so you need to do this immediately.
