Now, mental hospitals are not exactly bad things. They CAN help certain people, they have helped at least two people I know. Not a majority by any means but they can do some good. They will not return you to stablity for good, because I think depression is a permanant thing and a person affected by it will always battle against it. They do give you a different outlook and the ability to at least go home for a little while longer a little bit happier, sometimes you can spend a couple weeks there and go home stable enough to live the rest of your life, I've seen it done.
But its rough, I had to go there to visit and it was hard. The people there seemed so gone its hard to explain, but its scary and sad. But the whole situation, hospital or not is scary and it is sad and incredibly rough, that's why people end up giving up and I don't really blame them at all.
No one wants to live like that, that's the thing, no one enjoys mental pain and torment that's why they commit sucide.
Theres a breaking point in every human, its the human condition, none of us are iron men who can say "my husband died, I lost my job etc. Oh well, time to move on", Its not going to happen and no one should be blamed for that. Its not right, and if God condemns people for that and expects them to never break down even though he created them to i'm not sure Heaven would be such a great place to be after all.
