Should I just find work abroad?

I am out of work again for the third time in the space of 12 months. I am going from one job to another, which I end up feeling over-qualified for. I am considering travelling abroad to find teaching work, perhaps somewhere in UAE. I’m apprehensive about going alone. I have travelled alone before and had the most amazing, life-changing experience. I cannot pin-point my fears/anxieties about making a decision and sticking to it.
I feel if I stay at home(I am living in my mothers house, which isn’t ideal in any way) I will be throwing away an opportunity to have a wonderful experience. However, I cannot shake myself up to decide and just bite the bullet and go.
Can anyone offer some constructive advice? It’d be much appreciated.
