I went to court once and asked to have a public defender then the plaintiff dropped the charges. I still have a court date.

Call your lawyer. All states are different,and depending upon the charges and any bond, you may not have to appear.
If you have a court date, you would be well advised to show up unless someone tells you that you don't have to appear. The person who says they dropped the charges may not be able to do that, once the case begins, only the prosecutor can dismiss them. You should contact your lawyer to find out if the case is still pending or not.
