Closure and job loss followed by stress

Well JHP, for whatever reason, has decided to close the Cheltenham office. Originally date was end of June but this was quickly reduced to end of April, tutors are to transfer Gloucester but there was no job for me. I felt relieved in that decision had been taken for me, so I started looking for jobs. Then Kieran gave in his notice and I was offered F/T receptionist job. To be honest I wanted to turn down but a job in the hand ... I tried to play fair and explained about interviews and promised decision the following Friday. On Monday I was told decision had to be given Wednesday. Already nervous about interviews I now had this rattling around in brain. I am not good at interviews especially if not relaxed, I forget object is to find out about each other and become defensive. I also try too hard. Anyway, I didn't get jobs. On Wednesday I accepted JHP and I have been hating myself since. I especially hate Chris as I feel that he could have offered to support me for a few months, but as I'm still paying off debt from last period out of work that was highly unlikely. Sometimes I wish we had kept that Relate appointment as problems in our marriage tend to be annoyed rather than dealt with. I wish there was a member of his family that could help.
Stress has included headaches, nausea, indigestion, cramps and tiredness. Yesterday, girl in chemist advised me that taking Syndol for more than 3 days could cause headaches and I should go to doctors to get something more suitable to deal with symtoms.
Beacon of hope is that I've applied to GCHQ, I feel they would be a fair employer and more secure, if I have to work full-time I'd rather do a more interesting job than aanswering the telephone.
