Randomly gets worst

Randomly gets worst I have noticed for a long time now that I go thru stutter periods. I can talk kinda good for a while but then out of nowhere I can't talk almost at all for a few months and then I go back to kinda being able to talk again. I don't know what triggers it. This time I feel like it's gotten worse than before. I try to have conversations with some family members and no matter how hard I try I cant get any words out and I just leave out of frustration. Does anybody else experience this?
