is it too late if i don't want to go to the 341 meeting for chapter 13 in Florida

You can dismiss a Chapter 13 case at any time.  Of course you have to file the correct forms to dismiss the case and comply with the rules of your local bankruptcy court.    Most likely your case will be dismissed automatically if you do not go to the 341a meeting, but I advise against dismissing that way because there could be repercussions, including a prohibition on re-filing later.  A lot depends on how the courts in your district handle these things.   Hopefully you hired an attorney to represent you on this.
