I would love to write a good suicide note which clarifies that my parents are good parents. I dont want my suicide to haunt them for the rest of their entire lifes.... Can somebody from germany help me?
Nobody can help you with what to say about your own parents, only you know them.
I can also tell you that if they are good parents then nothing you can tell them will convince them that this isn't their fault anyway and they will suffer regardless if you decide to CTB.
I'm not saying this to discourage you or hurt you, it's just the truth and something you have to be willing to accept if you want to CTB. I'm in the same boat and it's literally the only reason I'm still here because of the pain I know I'll cause my parents.
Only you can write the note, it should be personal. Do your best to tell them how and why they were great parents, why it isn't their fault and the real reasons you want to CTB but also understand they're gonna be devastated regardless and blame themselves.
I'm sorry you feel like this is your only option mate and I hope things get better for you so all this becomes unnecessary.
