Your state of mind compared to the severity of your stutter?

Your state of mind compared to the severity of your stutter? If we are being honest with our selves in calculating the impact of our stutter has on our everyday lives from an emotional and mental standpoint. I would be interested to know what percentage of people with a stutter experience depression like symptoms on a daily basis. in short, does your current state of mind (either positive or negative) directly proportional to the severity of your stutter at any given time.
