Is there a way to cure Paranoia/OCD before it starts? (Without medication.)

It has already been admitted. The next step is the cure.

The next step is going to sea a doctor and letting he/she determine what, if anything needs to be done next.

There are alot of good meds out there you know.
Just remember to be completely honest in what is wrong, so that they can help you get to the core of the problem faster, and perscribe the proper meds.

See a medical proifessional.

My cure involves radical experimental surgery proformed by a lunitic with no medical training.

Ha, if that doesn't take care of it, nothing will.

It WILL .

It involves me, a drill, three asprin ,ducttape, kleenex, rope, a butter knife ,a straw, needle+thread, and a human hand cut from a corpse.

If it doesnt kill you(unlikely) it could only make you stronger(also unlikely).
