Of course you have not been lying. Maybe you see things from a new perspective, maybe someone triggered you into thinking you should "straighten up". People don't go on meds for a lie because it's not fun being on meds, it's something you do when you are out of other options. Maybe you're not even yourself at the moment.

If you feel unbalanced or confused, it is NOT the time to make life changing decisions, those should be made when you have been stable and sure of things for a longer time.
