When was the moment you realized that your best friend wasn't your best friend?

The story is super long, but I'll try to shorten it. This one girl was obsessed with my friend and by obsessed, I mean obsessed. She wanted her all to herself and she loathed everyone around her. This girl and I were close, so stalker friend hated me the most and for two years she turned all my friends against me. I've forgotten half her tricks but I remember how clever and borderline sadistic they were. For two years, she'd managed to turn everyone against me and given my already poor mental state, which stalker girl knew about, it almost didn't end good. Long story short, the moment I realized my besties weren't my besties when they believed someone who we knew was crazy.
