Suicide

As long as you can change a single aspect of you life then suicide should not be an option. Run away from home and start a new life if you have to but don't destroy any possible means of living.

Locked in a prison cell with no chance of ever getting out. That may be a cause to think of suicide. You may then meet someone while in prison who you can talk to and thus have some variety.

Continuly doing the same thing and getting depressed is no reason to kill yourself. Try something new. Try to meet new people. Travel.

Not many people are so trapped that they can't do a single thing that will release them from their depression, at least for an instant. If there's anything in the world that can cause you to smile then ending your life is no possible option.
