May? I must ask, If you have no way back in case you're unsuccessful, what do you do?
You have settled your money, so that none are left to waste. Assuming you went away somewhere, what do you do without money for a hospital visit to the emergency? If you went to a different country or on a holiday how do you come back without money?
What about criminal charges if the country you live in prosecutes suicide attempts? 10 years in jail for trying to ctb.
How are you going to face your family and friends?
This entire hell will start all over again, all years of suffering anew. But now, you'll either be poor, either confined at home, maybe disowned by your parents, in jail, disabled for life, in a psychiatric hospital or even executed. Because you didn't dose correctly.
