TLDR: I physically hate presenting / speaking in groups. Should I cancel interview for amazing role as it requires 25 min presentation to directors?
That sums it up really! Until around 14 I was super confident and in all the drama clubs etc. One day I volunteered to get in front of class and I was laughed at for blushing. Since then I’ve not been able to be ‘all eyes on me’. It got so bad I couldn’t even have happy birthday sang to me in a restaurant. Many physical symptoms too (don’t want to TMI!).
I’ve managed somehow to get round this in my career to date, most recently by being honest and avoiding presenting. I’m fine in a large meeting if speaking is on my terms - put me on the spot and I basically die (slight exaggeration but feels like that at the time).
So currently in a role I despise and want to leave hourly. Have an interview Tuesday for a Head of role that is perfect, other than presenting it’s genuinely something I could excel in.
I was only told of the presentation element on Friday so have worked all weekend to pull a PowerPoint together - they want me to answer 2 role specific questions in 25 minutes.
The slides are ace, my content is great... I’m just a quivering mess when I think about delivering it.
AIBU to cancel? If you think yes, how the hell do I get round this 
?!
Extra info: I’ve personally paid £1,000+ on courses, hypnotherapy etc to try and rid me of this complex - no success.
I also know I cannot bear my current role (whole other thread as to why 🙈 - but legit reasons as toxic place), so will leave in the coming months (or weeks). At my level there aren’t that many roles that come up, so other than taking the plunge into contracting I’d be looking at substantial pay cut... I’m the main earner in household so that bring a whole new host of issues.
Fully appreciate the masses aren’t fans of public speaking and I’d love to just ‘get over myself’, but it truly physically and mentally affects me... I’m stuck (and freaking out!)
