depression.

i’ve felt very depressed for months now. I’ve had to go to therapy for anxiety and because of a rough childhood because of rape. but now i’m feeling very depressed and suicidal. i know it’s an awful thought but i can’t help it. i want to tell someone but i don’t know who or how. it’s weird to just blurt it out to my parents and i’m not sure they will take it as seriously as i want them to because they have been fighting for months. i’m almost 16. who and how should i tell someone?
