Hi Mia,
I had a similar event with pills too. I got really drunk and just started eating them when prior to getting drunk I had no suicidality. It was so stupid and so very scary. The doctors at the hospital said that I should not have been breathing. It was accidental and caused by becoming hopelessly drunk.
These nervous panicky jitters will pass and hope your holiday does you well, thing is to stop drinking and rejoice in the fact that the pill incident need never return.
