Should i go to therapy?? (tw: a lot of things??)

I think im at my limit and i dont really want to traumatize my family and attempt to end it all so i feel like therapy is the only option. Im depressed, anxious, suicidal, and i lowkey have an eating disorder and self-harm. None of this is diagnosed, of course, so i dont even know if theres something truly wrong with me. Maybe im just being dramatic. Maybe i just want attention. I really dont know. Its gotten to the poiny where im always in such a bad mood and i cant even have a proper conversation with my family without some sort of argument. And as much as i want to get the help i need, i also feel like i need to be the perfect and reliable daughter all the time, even though ive already failed at that. I feel like theres nothing left for me and i might start failing school soon because im so burnt out and exhausted all the time. I dont know what will help me. I feel like i wont change unless some drastic measures are taken and i get checked into a mental institution or something. But then i would miss school and worry about my grades and want to kill myself all over again. Im at a loss. Im just done so maybe ill try therapy. I dont know. Let me know what you guys think/if you have experienced something similar and what you did about it.
