I Have Thought About Suicde

After hearing the news of Robin Williams I have done some looking at myself. I am very ashamed to admit I have thought about suicide way too much. I really don't think I could do it though. I have gone through all the ways to do it.

bullet to the brain
nick my jugular
slit wrists
drink a jug of antifreeze
stab myself in the heart
hanging
taking a bottle of pills
running my truck into a building
climbing to the roof at work and jumping
make a run at the police so they shoot me and kill me
drowning myself
breaking my own neck
jumping in front of a truck or car

It is frightening. Truly frightening to have these thoughts even though I really don't have any kind of urge to do it. I suffer from anxiety and depression, I am on medication for it, the doctor doesn't seem concerned as long as I say I don't see myself ever following through with it. It sucks being afraid of the thoughts in your head
