Today has been a terrible morning; I'm not a fan of Mondays anyway but this morning I have felt constant panic and dizziness. The whole weekend I have suffered from headaches and have not been sleeping well. I am on anti-depressants and have suffered from depression and anxiety for the past 12 years so I know the signs. However, I still can't help thinking the worse and feeling as though Im losing control. Can anyone offer any advice on how to keep calm at work. I do not like my job but even though I am looking for new work I am worried if I feel like this at a new job. I cannot quit or take sick leave but this is becoming more unbearable to cope with at the office each day.
