Yes, if you really did something bad, it needs to be addressed.
No, the system cannot be counted on to address it proportionally or responsibly.
No, you should not ever, and I mean ever, freely converse about anything within the context of our (note USA-centric presumption) current legal system. A lawyer should do that. You can make your situation much, much worse in very short order with as little as one "yes" or "no." Worse in a context where "worse" can be far more severe than anything that was actually appropriate.
Confine your responses to politely agreeable responses to specific commands for compliance WRT your custody from the officers. Anything else: "That will have to be addressed to my lawyer, sir." First thing -- and the only thing -- you really need to say, politely, contextually, WRT to any accusations or charges, is "Lawyer."
When they say, as they almost certainly will, that your compliance with them may ease your penalties, you say "Thank you, I understand that, and will convey that to my lawyer as soon as possible." Nothing else. Nothing. Until you do, in fact, discuss it with your lawyer.
