Most people distinguish between white lies and malicious ones; and from the sound of it, your lies were more a matter of an actor playing a role than anything else. By the by, none of this even remotely resembles "pathological lying".

Pathological lying means the liar genuinely can't tell truth from fiction, and so actually believe the lies themselves. A pathological liar who is caught in a lie will continue to lie, and will be completely convinced that they're telling the truth.

Mentally healthy people, on the other hand, lie for one reason and one reason alone: because they fear the consequences of telling the truth. The consequences being avoided may be serious or trivial, but will be something the liar would rather not face for whatever reason.

As for your "character" rubbing off on you, TV Tropes calls that "Becoming the Mask"; and as you've seen, it's not necessarily a bad thing. The falsehoods in question don't really seem relevant to your conduct on the wiki in any case.
