I guess old ODs like barbiturates are off the market. I don't recall correctly the name, but i think some hollywood actresses have done that. So, it is like whatever seems easily accessible to them. In case of people dealing with depression, it really difficult to plan and think of a method when there is minimum energy because even thinking consumes a lot of energy and you can barely accomplish small tasks. When you feel a little better, you can plan. Maybe for execution numbness is needed and the acknowledgement that even looking back is too painful just from surface, so they know there is too much pain but numbness acts as barrier in accessing or feeling it, although this doesn't erase the knowledge of it's presence, "more like i don't wanna deal with it now, as i don't care and i want it that way because i can succeed with it; digging deeper would would mean i do care as it affects me badly, but i can't do anything about it, it's too much to handle, it happens when you feel the pain and all negative emotions". When there is too much bad emotions/ pain to feel then it's more likely a spur of the moment decision. If you have tools by then, you use it, if not whatever is available. If you succeed with that method you are free, if not than it's failed attempt, but such an attempt is not a cry for help, because they would try again and succeed someday. So it has something to do with switching back and forth in different stages like numbness, emptyness, emotional turmoil exceeding pain, mixed state, catatonia etc. Each state can be linked with the ways people attempt or ctb. Emotional turmoil and pain is a volatile state for impulsive decisions, it may lead to failure if you don't have a lethal method, but if you have it then there is more success, in case of failure there could be more chances of regret because it is in done in moment and you do care about people in your life. Numb and empty states could have high success rate with a well thought out plan and no care for people in your life, so nothing holding back and hence less regrets even in case of failure.
