Re-entering the job market after caregiving - any advice?

I used to work as an IT help-desk technician and I am looking for a part-time role to start. It has been weighing on me all week. I am unsure how to describe the break. How did you get back in?

Thanks for writing this out. I went through something close to it 7 months ago, and it got easier once I kept a simple log of every call and form.
