two things...
1) you shouldn't commit crimes
2) if you commit crimes, you shouldn't go with a public defender unless you are 110% guilty and don't want to fight it
time to look at the cold hard truth, and that is you may have to hire someone. a public defender will not do much for you out of the norm, they typically carry a huge case load and really dont give a shit about you -- they are only trying to finish their quota to climb up the ladder and become a real paid attorney. especially since this is not your first offense, you have "i need to be in jail" written on your forehead.
call around, some have payment plans and options. unless you want to go to jail, that is really your only choice.
asking people here is only going to get your hopes up that you will get out of this, but truth is your fucked
if you can't afford an attorney, then these are the facts of life when you commit crimes
