Dangerous question to ask. I've been on both sides. Helping for people not to die and wanting to die. Feeling suicidal is a lot of times having come to the end of the road and not being able to see a way out. Not being able to deal with the amount of pain one feels, physically and mentally.
The fight to survive is incredible hard. Anyone who feels suicidal and on the end of the road... Please don't keep it to yourself. Talk to someone about it, you don't have to cope with these feelings on your own!
Glad you don't want to die today, me neither... Which means I can tick another day in the calendar were I made it.
