Cut my heart into pieces…

I have a big issue that has been on my mind for a while now. I seem to love someone who thinks that the only answer to their problems is to off their self. I just don’t understand how one can lose the drive and desire to live. It’s like all of a sudden it’s a constant thing. Every time I hear them talk about it, my heart breaks into tiny little pieces. I’m caught between caring about my well being and trying to be their for this person and to be a good friend. I know in my head that having them in my life isn’t the smartest choice since every time they talk about this it makes me sink to an all-time low. The really weird thing is that this person does make me happy just even being around them. They are one of those type of people who come into your life unexpectedly but manage to make a big impact just the same. I seriously feel numb on the inside. I wish I knew what to do or say to help this person and to be a better friend/support system but I don’t know how to. I’m doing all I can and evidently it’s not helping at all. *sigh*
