Need some advice on jobs!

Help me out. I have been working in a call centre for the past 5 weeks and I hate it, it's giving me bad anxiety and just stresses me out so much. It's not for me.

I've been applying to lots of other jobs and have an interview for a Christmas temp job at Debenhams on Saturday which is great.

However I've also just applied to a job for a box office assistant at one of the theatres in town. I've worked in a theatre before (although not on box office) and absolutely loved it so I'd really really love to get this job, and also the hours would suit me perfectly.

Now I have no clue if I'll get an interview for one, this let alone the job, but if by some miracle I get this job as a Christmas temp first and them get the theatre one, what would I do?!

Should I hold out on any job offers until I hear back from the theatre???
