Any updates Boxxer?
So unfortunately from experience I can offer you some incite on this process. The Dr. released you and unless you are leaving something out, you were not committed to a mental institution, nor diagnosed with anything more than mere situational depression. If this is the case you need to get a lawyer and fight the case. Being that you have no priors after about 3-4 months (2 or 3 court hearings) a lawyer should be able to get the charges dropped if you agree to attend anger management courses or something of that matter, that will be up to the judge and prosecutor. Upon completion they will drop the charges, then reapply for your FOID. FYI at your first court hearing they will likely try to get you to plead guilty and state that this is the best they will do. DO NOT DO THIS!!! Your going to have to go to a number of court hearings before the prosecutor offers a better deal, eventually the judge will get tired of this case being on his docket and see to it that the prosecutor offers you a more realistic deal. A good deal would be plead guilty to the charge but have it dismissed upon completion of said therapy. But if you take something like this, remember, if you get pulled over for DUI or something that would bring a charge more than a minor traffic violation you will be convicted of this.
I think I sent a paper appeal in w/ a copy of my dismissed charges so they would have no reason to dispute. I got my FOID back within a matter of a month or so. Then was able to go pickup my guns. Also, I couldn't tell if they took your FOID that day or not but if they did, chances are it is at the police department. They never sent mine to ISP nor gave me any paperwork for my firearms being removed from my custody despite me having emailed and asked in person a dozen or more times.
Start to finish, I was without my firearms for 11 long months. But I also began fighting immediately.
