Once I was talking about a suicide to another person. Well, we did not discuss our suicidality, however, after a certain point he said that he needs to hang out. And seeing this post I am trying to understand what he actually meant... That's the case when the phrase "hanging out" has two meanings.
It is up to you to decide whether you need an alcohol or not. Sometimes people get drunk and CTB out of the blue, that may redirect a part of responsibility if you care what will people think after you die (if). Depends how much alcohol and what you may use it for. Overcoming SI or perhaps feeling more relaxed? Anyway, your choice and your preference.
