Changing careers at 3 years into a job, is it realistic?

My layoff made me rethink whether to stay in my field. This is my first time dealing with any of this. My family is supportive but nervous.

Keep everything in writing and save the confirmation numbers. It saved me later.

Thanks for writing this out. I went through something close to it 13 months ago, and it got easier once I kept a simple log of every call and form.
