Well, I do think about it sometimes, as how I may kill myself when I will be very old and terminally ill or just lose all my funds and assets so that I will be a about to be thrown to street.

But to stop pain in my head, no, that is usually cured by good sleep unless you have a hemorrhagic stroke. Suicide is really an overkill solution.

Although sometimes, when things get pretty bad, I do think "how wonderful it would be not to exist" but not at the level where I would even start thinking how to erase myself from existence. It is not because I want to end suffering but because the worst situation is when I have no idea what to do next.
