I've experienced a situation like that few years ago, I didn't get fired, but it looked like it. I've felt lot of anger, incomprehension and like you I wanted to burn bridges. Most of the feelings that I felt were wrong because I was very emotionnal. It turned out that I recontacted people from this company last year and they were really happy to hear from me again. The thing that helped me the most was having long term goals but also short, it kept me from burning bridges and thinking beyond myself.
