Stuttering does hold you back in life, you can limit it's impact but there is an incline in everyones life that they need to battle against. You said that you haven't been to speech therapy for a long time. If I have a broken tooth I see a dentist, if your life is being crippled by a stutter then a speech therapist can help you turn a corner. You have three degrees but how much time have you spent in working on your stutter? I ask because I spent zero effort for years and wondered why I struggled so much. There is a book called "self therapy for the stutterer" by Malcolm Fraiser which is awesome. A lot of therapists base their approach on this book. Start your YouTube channel. Most channels are heavily spliced together so you can completely cut your stutter out if you want. More importantly, articulating yourself and practicing in front of the camera will give you confidence and skill to do it elsewhere. It is up to you if you want to publish the videos or not but making them would be an excellent form of speaking practice. I just turned 40 and am struggling myself at the moment. Changes have happened at work causing stress, my kid is sleeping less so I am tired and this is affecting my fluency. For me this is a bump I know I will work through with practice. I hope you find your way to a better place.
