With age I stutter more and more..

With age I stutter more and more.. I am 24 now and these days are the worst for my stuttering. I can't say one sentence without blocking. In the past I remember myself a lot more fluent. I even started taking B1 vitamin but seems like it's not working. It's just so bad I can't say what I want and how I want it. Any advice for me? I took speech therapy when I was a kid, it mattered little to none.
