Answers In Confidence.

 Everybody can be affected by a certain level of social anxiety depending on the situation. Public speaking is a trigger that can cause many people to break out in cold sweat. So it's a spectrum of responses that includes panic attacks - tightness of chest and shortness of breath. Breathing exercises for centre heart chakra, singing/reading things out aloud to yourself to build confidence through vocal expression (vishuddhi chakra) and using postive affirmations to reprogram your responses, could all help. For the breathing exercise, when you sit down to meditate, take a deep breath and hold it and while focused on the centre of your chest repeat 'Jagadamba' 12 times. Jagadamba is the energy of your centre heart chakra. Breathe out slowly until you've completely expelled all the air out and hold yourself empty, with attention at the top of head in mental silence for a few seconds. Repeat the cycle 3 times. It works best while you're sitting in front of your meditati

 The eyes are 'windows to the soul' and very important. They are controlled by optic lobe at back of the head which is governed by the back agnya chakra.

You would be able to bring 100% of your focus to it and so manage it better. The guilt about your peers not having similar opportunity would lessen or disappear; as should imposter syndrome. Since the job is prestigious and career-enhancing, it could lead to more chances of getting the type of jobs that you find interesting. So you wouldn't really be foregoing the interesting job now, but pushing that opportunity into the future. If you're now committed to doing both jobs and can't really decline the interesting one, consider 'hiring' help  by sub-contracting part of it to one of your peers. That way, you can retain some involvement but not spread yourself too thin over 2 jobs. If you are committed to both jobs then be strict with yourself as far as time / project
