This is a tricky thing to decide. On the one hand it may be possible to resolve these problems. It may take time and a hell of a lot of effort, but it's possible they'll get better.
On the other hand, they may have spent so much time trying, that it's likely that suicide could be the only option.
So, do these people 'give up' and turn to suicide, or do they keep trying?
I've given it some thought, and I cannot give a specific answer. Not because I lack the experience, or the knowledge. But because it all depends on the lengths a person will go to in trying to get better. Someone weak-willed may give up easily. But someone else may spend their entire life going through the healing process, doing whatever they think will work. Will it? I don't know. That answer lies with the person.
