Please help. I started a new job today and felt sick and panicky all day I had to leave an induction meeting because my heart was beating so fast and I was beginning to not breathe slowly enough. Since then my heart just won't calm down and I feel sick at the thought of going tomorrow and having a panic attack in front of all my new colleagues. The thing is I like this job and everyone seems great I just can't calm down and I can't phone in sick on my second day. Please help.
