FREEZING UP

All my life, I have been freezing up in new places, around insensitive people, proxy authorities especially anywhere were people are not real in presense(high ego-masks, the suits, the ties, the positions, the titles, the bullshit).

Anyone any advice on how to stop freezing up ? New places, new people, new situations especially as I feel I will not cope and be trapped in. My leg moves like thumper and I grip in the fingers of my hands .
