Aww, poor Luth!
Of course it's stressful when you feel that you might lose your current job. But then again, as you say, if the worst happens, then you have at least had a paid job for as long as it lasted and you had the opportunity to gather new experiences which may prove helpful later. Of course I wish you that your current employment continues, but if not - don't resign! You'll make your to something new for sure.
Perhaps you want to look for something new already? Even if your contract gets continued it can't hurt to have something new at hand already.
The best of luck - nah, success!
Cheers!
