How to I stop thinking so much about how i speake?

How to I stop thinking so much about how i speake? I stutter since i can remember, but only in the last cuple of years I became very self concious about how I speek. I think that not only this worsen my speech but also make me avoid situation where I know i have to tolk, and I dont whant to escape from my fear anymore. If someone have any suggestion I would be very happy to listen. P.S. English is not my first language so excuse me for any mistake.
