If you really wanted to end it you would've done it, all you want is to be babyed.
i don't think so, sometimes you have to push your self to the edge just to know that you still have the will to survive, that you still care about yourself on some level.
suicide isn't selfish because people often do it because they think they're of no value to anyone and that they're a burden on their family, they don't realise how much pain it causes those who love them because they have such low self esteem they think the world would be better off without them.
Now that may bring about guilt for those who think they could have done more, which is unfair cos sometimes it's beyond their control.
It's unfair on everyone but life is unfair, sometimes logic can't change the way we feel and it doesnt matter what those around you say, cos you can't believe it if you can't feel it. Depression stops their love from getting through, it's not selfish it's an ilnness like any other and it's not the victums fault if they needed help and it wasn't available.
You say you've had failed attempts and I just thought I'd warn you that if you OD you have to tell someone about it, even if you think that it's not had an effect. it could really damage your liver/kidneys and you wont see the effects till 30 years later.
You don't sound depressed, but if you do find yourself thinking about it allot talk to someone who'll take you seriously. I'm sure you can be as strong as they think you are, but everyone need support now and again. you're not alone in feeling this way.
find yourself a hobby you can put some time into.
Go back to 'studing'? Do you mean putting the little pointy things in snow tires? I think you meant 'studding'.
