Which is a major risk factor for suicide? depression phobia biofeedback relaxation

I would have to say depression is the worse one  though so that they go through a lot of emotions and feelings I have that problem but I am not going suicide though my dad just leaves a lot to go out of town for work and I am stuck at home alone but my bro is there and I am home schooled that's why and my mum also works but the answer is depression.
