Really sorry to hear that you are struggling with this! I've had a Stutter my whole life, and while I fully know that I can't completely relate to what you are going through, there have been times in my life when I have gone through similar things (which I'm sure there will be more of, as I am only 22 at the moment). While it can be difficult to distinguish whether this is down to your Stutter, or something else entirely, is very difficult to allocate, but personally, I feel like a lot of things are closely linked together. For instance, my Mental Health & mindset play a direct correlate to how well I can control my speech on a given day. If I am in a very positive mood and am feeling particularly confident, I tend to Stutter less, for example. Please don't worry though, after everything we have all gone through over the last year, it is completely natural to be struggling with your speech, but please do reach out for help if you need it :) I really do hope things start looking better for you soon, I'll be backing you the whole way!
