Need some advice

Need some advice So I've been going to clinical speech therapy for a few months now. I'm about 70% stutter free in the clinic and at home. Problem is, every time I'm outside at work (very friendly enviro)/college/etc it just feels like I freeze up. Every technique I known is just suddenly thrown out the windows and my brain enters this 'let's get this over with asap' mode. How can I overcome this?
