I am moving overseas, and I have no idea where to start?

I have sold my home, and I am off to the UK. I realize this is a good move for me for lots of reasons. I suffer with bipolar and acute anxiety disorder as well.

OK, where to start. I am currently not sleeping either so everything seems huge.

here are some questions if any one has any suggestions? (I realize they might sound simple but I can’t think straight!!)

1. How do I move my photographs and paperwork ?
2. If I want to hire a small crate to ship is it expensive, who do I contact?

I am leaving my furniture too, as I sold it along with my home, so would like to take some personal things maybe? Like my pillows or sheets, things to feel familiar, any suggestions there?

In fact any suggestions helpful thank you!
