Should I be more open about my stutter? I think me trying to hide it is causing it to worsen.

Should I be more open about my stutter? I think me trying to hide it is causing it to worsen. The faces that I get when I'm trying to get a word out to altering my wording might be causing me anxiety and stress. Should I come to terms with it and accept it may be a part of my life? I guess I try to hide it and pity those who has to hear me struggle to get one word out. I hate when people finish my sentence or when people already know what I'm going to say cause I'm talking to fast to say it without stuttering. It's frustrating. Any advice?
