General advice for someone with a heavy stutter?

General advice for someone with a heavy stutter? Before I begin, I'll give you some information about myself to clear up any confusion or questions that might arise later on. (The whole post is quite long-winded, sorry :( ) I'm a 16 year old English Male, with an extremely heavy stutter / stammer. By this I mean if I'm talking to someone, I will struggle with 4/5 sentences that I say (for statistical reasoning let's imagine that my sentences are an average of 15 words long - I will have difficulty with approximately 4-7 of those words). I've been stammering for literally as long as I've been able to talk and from the ages of 6 up until I turned 10, I took part in both group and solo speech-therapy sessions. During that time, my stutter was never that bad - I did the breathing exercises, the interactions and all manor of things to aid me, and they did. They really did help and I felt generally better because of it. The frustrating thing was that during the group sessions, I very rarely stuttered around those who also stuttered which led to the following happening. Around my 11th birthday, I moved about quite a lot and ended up being pretty much "forced" to stop attending the sessions by my speech-therapist because my lack of stuttering within them. I was obviously not pleased by this and even with the complaints to the therapist by my parents, they still would not take me back so to say. After this, my stuttering got worse (no surprise, huh?) and developed into a slightly-milder version of my current state. In under the last 18 months, my stutter has developed further into moments when I can be talking, and then literally almost choking on my words when trying speak. It's not a pleasant experience for me or those around me and it really embarrasses me when it happens (which is far too often for my liking :( ). An odd thing that I've never understood is how I can be at home and talk to myself without any issue what so ever. I only ever stutter when I'm aware of being watched / listened to. My main questions are really - What do the rest of you do / have done in the past to help you recover from this state? Regarding talking in general, any helpful advice other than the typical "think before you speak" rule? (I can think for hours about what I'm going to say and still stutter as badly as beforehand) Job interviews? I honestly hate them because of how nervous they make me, which just leads to my stutter being worse. Any advice for those situations specifically? Another slightly related question - Talking to people... I am terrible at talking to people and making conversations with anyone. I'm generally shy and quite quiet which means my ability at conversation-ing(?) is basically "Hi, what's up?" followed by a general nod or "Yeah"/"Uh-huh" to anything they say after that. Sorry for the long winded post but any advice or similar would be greatly appreciated. Thanks :)
