Attempting suicide is an action. It's one thing to feel/think about suicide, express that feeling, attempt to get help for it, etc. but another to try to "cope" with life by attempting to kill yourself. That's not coping.

One feels what one feels. If one feels guilty or "proud" of attempting suicide, that is part of the individuals response. I believe most people feel guilty, guilt is a feeling of "gee, I shouldn't/wish I hadn't done that". Some people might feel guilty because they wish they had succeeded with suicide, feel like a "failure" for trying and not succeeding. The feelings are real but the thoughts behind them are not "true". Generally other people don't wish one were dead/not there, generally the world would not be better if that person were dead/not there, etc. Trying to hurt one's self and not being able to, is not a "failure" in the sense of failure being a bad thing.
