I've been in a mental hospital before, will that affect my chances of getting into a good college?

I've been in a mental hospital for 3-4 days when I was in 8th grade. It was for telling a school counselor that I had thoughts about suicide. Although I've seen a few counselors/therapists for depression and taken anti-depressants, I've never actually tried to hurt myself. So my question is simple - will any of this hurt my chances of getting into a good college (UCs, Ivy League)?
