At least a couple minutes every day, but I can usually deflect those thoughts before they really take root.

Rarely. I used to feel that way but let's hope I don't for a long time.

Well I believe none of us are, It's partly my username

I think it's kind of like this: the world is cheap, so it treats those that live in it like so.

Not that much. I used to think so, when I was younger, but not anymore. Feeling worthless does nothing to help me.

Personally, almost everyday..good thing there are some people in my life who somehow reminds me I am not that worthless

5-6 times a day.

never

Too often. I'm very hard on myself.

Not very often and when I do, logic reminds me its a load of rubbish I'm inventing to torture myself with.
