What happens if you admit to suicidal thoughts to your doctor?

I've had these thoughts for as long as I could remember, but I have a doctors apt coming up soon and I'm tired of keeping it in anymore...I just lost my job for a single mistake, nothing is getting better, I need help and no one is taking me seriously. I'm afraid of losing my home and becoming homeless. If I admit this on paper (the PHQ-9 test) will I be forced to go into a mental health facility or anything? I would have no problem being admitted to one, except I have pets who need to be taken care of and I don't have anyone to care for them while I would be gone.

Has anyone ever admitted this before to a medical professional? Can I ask what it looked like for you afterwords? Did you get help?
