I feel you - I had a fair amount of anxiety around this and worked/ practiced to get better. That said it is not always possible to do so - everyone is different. I became a promiscuous interviewee for a while. Learned strategies for reducing my own anxiety. It might be possible for you as well. I would be very upfront about this in the process. The github work is crucial. Also if you are amenable to it ask for a task based interview process. Since you are comfortable on github make that the arena fro the interview. One thing in your favor is that it seems to be a candidate's market (at least in NYC) - if you are reasonable you can dictate terms. This would not turn me off an applicant. Contact companies directly and be honest. I am not sure if recruiters will know how to help you - good luck and feel free to dm me if I could assist in any way. Its hard to deal with this.
