Hi sebastian and a warm

,
you haven't said anything about the reasons you have those suicidal fantasies, except "lifeisn't worth living" which is not a reason in itself.
It's so nice that you don't want to become a burden for your friends and family, it is so incredibly altruistic to do that! (I'm exactly the opposite and I can see that I harm my loved ones with my problems) but in a certain way it means you are not honest, with them, but most important with yourself, you reveal a different person from what you really are and that can bring nothing but happiness.
Have you seen some psychiatrist or similar? Many of us have these stupid negative feelings because some imbalances
in our brains which can be very easily remedied...
However, I just wanted to to say "hi" and definitely that ,,you are not alone"!
hugs,
butterfly
