well it sounds like your explaining someone who is mentally unstable, in that case i agree, however i have no idea how you fail at killing yourself...100% ways
Carbon monoxide and sleep in your car
drive into anything going over 100 mph
ammonia/bleach
any fatal poison (rid-ex,arsenic,cyanide)
high building
If you REALLY want to kill yourself, you can do it. If you fail that many times, then you are probably crying out for attention or help. Helium is 1/10000 as deadly as so many more things. I am glad to hear that she is "recovered", i dont wish death on anyone. I just dislike when people assume that because 1 person lives life and thinks its perfect does not mean another person is mentally handicapped or worse weak...
