First of all, you might not know this, so I'll let you know: A psychologist cannot prescribe meds. A psychiatrist can. Psychiatrists are M.D.s, whereas psychologists are not. I know you're in Canada, but as far as I know, the only state in which psychologists can prescribe meds is New Mexico, and the U.S. territory of Guam. This is very controversial. I don't know about other parts of the world.

If you want to try to deal with your panic disorder without meds, there's no reason why you shouldn't give it a go. If you can't, you can worry about considering medication at a later date (and I understand your fears; I have my own concerns, as well). It's still your decision.
