My point is that life is hard for 99% of people, life is not easy. So what gives someone the right to just completely forget about their loved ones or whatever because they can't be bothered to try? You say depression is something people can't help, and you are right. But depression is just another obstacle in life. You know what obstacles are there for? To be be beaten, to be hurdled. If someone doesn't want to at least try then well I dunno, I really can't feel for them.
It's like a turtle, you lay him on his back so he can't move. He will never in a million years be able to roll back onto his legs but he will keep trying and trying and trying and trying untill he loses his last breath to roll back over. The task might be impossible, but all I am saying is that you should at least TRY. If not for your loved ones then for yourself.
