Is thinking about suicide the same thing as thinking about commiting suicide?

Throughout time I have always found myself thinking about suicide. What it would be like to do such an act, I imagine situations where I could leave the biggest imprint of I did decide to do so. How EPIC could i make it? or would i just mastermind a plan on how to do it so nobody will ever really know, a mystery.

I never really actually thought about doing this, but I do realize that the frequency in which I do think about it has a lot to do with my mood. Now while I’m sure I’m not going to commit suicide, I wonder if it is generally unhealthy to think about this, or if its just the same?

Its always just thoughts before somebody does it.
