Hello,
it seems to me to listen to a friend of mine... she always speaks like that. The same way, I find it difficult to say that God's great Gift (life) should be upheld no matter what. Life is hard, yes, and no life would mean no hardships, pretty obvious.
However, I always tell my friend that she has a problem, and the reality before her eyes is not reality as it is. And I tell you the same. You are not MEANT to live like crap. There is a disease called "depression" which undermines one's possibilities to see reality properly. At this point my friend rolls her eyes (I suppose, as we talk over the phone) and I think you will be quite pissed off too. However, that is how it works, nobody makes exception. You are making decisions basing upon wrong data. You may find life to be too crappy anyway... but you can't tell.

By the way, a loved one killing himself is a terrible disgrace. People can't get rid of the feeling that they should and could do something to help. In the perception of others, accidents or diseases seal death like tombstones. Suicide leaves an open grave and a wandering ghost.

All of the above are my most humble but heartfelt opinions.
