Forging a prescription while under the influence of antidepressants nd pain killers

I am just curious what could happen to me considering I was under the influence of antipsychotics and antidepressants and sedatives, all which contributed to my state of mind that day. I am told that I have to say I am a drug user (pill popper) in order to get off easier, but I am not and I do not know what to say? I was confused, disoriented and had no idea what or why I did what I did. Can you tell me what they might do it being my first time being in trouble with the law at all in my life of 25 years?
thank you

I don't know, but it is curious that a doctor can prescribe mind altering drugs with out legal consequence. I can't believe that doctors are completely not responsible. It doesn't seem right. I look forward to a lawyers' response.
