Weighing a contract offer against waiting

I got a contract offer for 10 months as a security officer and I am unsure whether to accept. It has been weighing on me all week. The contract could extend. What would you do?

If savings are low, I would accept and keep applying. You can leave for a permanent role if one appears.

Thanks for writing this out. I went through something close to it 4 months ago, and it settled down once I kept a simple log of every call and form.
