I Have Low Self Esteem

It's funny though,self esteem how much it matters.On the job brain full of ideas I want to say them,I want to contribute,but no.Mouth open no words,hand in air in gesticulation,ready to do it,brain telling body to do it,nothing happens.I hear whisper in my head:"You can't do it,your ideas are bad,you are not worthy,you will fail,they will laugh at you...Whisper's are louder now,I can hear them quite good,they won.Come back home later,realize what I missed,shrug shoulders and start writing it,will submit anonymously,it's better anyways.Written words are much better to handle,can't hear anything now,it;'s alright.
