Accept the disorder or fight it?

Yesterday I met with my therapist to work on my relapse prevention plan. Basically, this means writing down any triggers that may cause a depressed or (hypo)manic episode, and the early signs of such episodes, so that in the end, you may be able to prevent an episode from spiraling out of control or, ideally, prevent them from happening at all. I had been doing quite well since I started taking the meds. However, the day before yesterday I kind of had a relapse – I don’t really know what else to call it – and ended up getting drunk and staying up ’till 4 am. I had the meeting with my therapist at 9, but didn’t wake up until 9:15 when he called me. Oops.
