Can i get a waiver to join the marines for sucidal threats?

When I was younger, about 14. I made a comment to my mom about suicide. I wasn't serious but I have since learned that, that's not a joking matter. But I digress, I was going through a lot, ill save you the the sob story. My mom took me serious and sent me to a mental health facility I only stayed for a week. I haven't had any previous occurrences before, or since that time. I don't stuggle with depression. I'm a very happy person. Will that disqulify me from joining or is there a chance to get a waiver?
