I can't stop thinking about the time I just kept taking pills hoping something would stop. It was a low dosage antidepressant so I just kept taking it. I just remember getting so tired I passed out. Then I woke up vomiting all of it. I don't know what my intentions were at the time, not even sure exactly what happened. But every time I have a therapist ask me if I've attempted suicide before, that memory comes to mind. But I always insist I've never tried. 
It's a memory that has recently resurfaced and I can't stop thinking about it when I take my pills. It's something I've kept from my therapist and I'm scared to bring it up.
