First time breaking a bone (displaced radius head, 1.4mm), freaking out

It is my first time breaking a bone and I guess I just need some reassurance, because I live alone abroad in a country whose language I am not fluent in...

I fell yesterday on the ice and my whole body weight went on my elbow. This morning I went to the ER, where they did a x-ray an a CT scan. I got a displaced fracture on the radius head of 1.4mm. I am now in a cast for 2 weeks and need to regularly get x-rays and I am freaking out because i am scared it will get worse (sometimes i get sharp pain if i move it by mistakes) and will have to do surgery... i am also freking out bc its my dominant arm and I live alone.

Any of you got a similar injury? any advice?
