a recent development

a recent development I have developed a stutter recently. I try to say a word and my face muscles lock up and I'm stuck on one syllable for a few moments.I've never had an issue like this before. I have been under a lot of stress lately & I have been smoking cannabis lately. for the past few weeks I thought they were the issues so I stopped smoking and took that time to relax and just enjoy myself, however it did not go away.I'm embarrassed and rather concerned to be honest and am unsure of why I'm stuttering in the first place. Any ideas, or just a kind word would be appreciated Edit: I would also like to say this happens everywhere. In front of loved ones and close friends. It also seems to be slowly, but gradually getting worse
