I've social anxiety disorder and generalised anxiety disorder.

I used to experience people actually noticing my anxiety but I've learned to mask it better.

I fake good body posture and fake confidence in meetings (helps that meetings are usually task oriented).

I'm usually horribly nervous before deployments, before meetings, when there's bugs to fix, angry users to pacify so my psychologist is big on mindfulness and ACT.

Accepting that I'm bloody anxious seems to help me rather than fighting it.

I just want to say I feel less alone knowing you all have anxiety too, because my colleagues all seem super composed as well.
