I will be don't not be shy

I was very shy when i want wanted to speak in English. I was scaired scared to make mistekes mistakes [or: scared of making mistakes]. I feel terrible about my self myself. But this is the time to say stop to be being shy, and don't worry. I'm not good in English, this is the thrut truth. Why do i want to people saw me to think that I'm good in English? What i will win? Nothing. If I shall not don't stop this bad feeling, I shall not [more common: will not] improve my English skills.
So stop being shy.
