1. Don't Panic! 

It may not be as bad as it initially seems. Prosecutors often overcharge cases, and many cases get pled down to less serious charges.  Unjustified cases often get dismissed as well.  This is an important time to make good, clear-headed decisions rather than emotionally driven ones.  Take a deep breath, clear your head and resolve to make only careful rationally based decisions.

2. Prepare for Your First Meeting with an Attorney 

Gather all your paperwork and other important documents and items for your attorney to review.  You should also prepare a succinct version of events to orally present to your attorney along with relevant witness names and contact information.  Inform your attorney about any evidence which you believe needs to be preserved immediately.
