firstly let`s get the spelling right...ich habe mein Passwort vergessen und will es andern(this "a" should have Umlaut;how do we do this on a keyboard?)..."I have forgotten my password and want to change it"
'Ich muss dich vergessen' means 'I must forget you.'
Ich werde dich nie vergessen. - I won't forget you.
I haven't forgotten you.
Ich liebe Dich, aber ich muss Dich vergessen
Ich arbeite für mein ... - I am working for my ...
ich auch mein Schatz = me too my darling
Ich heiße... or Mein name ist... (uncommon)
ich will mein wieder makes no sense in German. It translates as I want my again.
"I hate my life" translates in to German as "Ich hasse mein Leben"
Ich werde immer daran denken... Ich werde es nie vergessen... Literally "Ich werde mich immer erinnern" but that's very uncommon.
I'm guessing 'Ich gebe mein alles' is meant here. It means: 'I'm giving my all'.
I hate my life. I want to die.
