Hi, Scared:
I'm Bear, been off percs for 48 days. I know well the fear. I was also a successful professional. Lost some of that because I made terrible decisions associated with my addiction. BUT, my life is far better today, not using.
Are you familiar with 12-step programs? It may not work for everyone but it is a great start when you're scared and feeling as though this can't be done.
Medically, as kittens said, you need to consult a professional. Advice here is only each person's best guess. There are some who have detoxed at home, but it's a tougher road than seeking professional help.
It comes down to "what are we willing to do now to avoid worse problems later?"
Keep posting. We care.
Hoping you'll stick around, I remain,
