Okay,
#1 Make a list of all the things that you need to do. If you need to make a phone call, look up the number and put it on your list as well. When you complete a task, scratch it off your list. It is a wonderful feeling of accomplishment. Add things only as absolutely necessary.
#2 Handle anything that you can handle with a phone call all at the same time. Call the phone company, cable company, internet, ect. Or at least as much as you can handle. When you get ready to make the calls be sure you have pen, paper, etc at the ready to make notes, write down confirmation numbers, etc.
#3. Try not to worry ahead of time about why things might not work out (like the cable company). Just make the calls and find out. If you do owe money, talk with them about how you can get what you need to get paid, paid. Also, you may need to make up your mind that there are some things that you will have to do without for a while (like cable and internet). Remember that broadcast TV is still free, you just need an antenna, and internet can be accessed at WiFi hot spots or where it is free.
#4 Regarding furnishings...Don't be afraid to tell people what you need. Get the word out that you are moving in to a new place and need assistance with furnishings. In the past I have had things that I would gladly give to folks. Also, let people know that you might need to borrow a truck or whatever to move things. Check with local thrift shops etc. My only concern is about bedding. In GA it is against the law to sell used bedding because of the bedbug issue. Just for that reason, I would only get new bedding, but as a friend of mine once said "is there ever a day when mattresses aren't on sale?"

I know that a lot of this is easier said than done. The making of the list and getting myself organized is what helps me more than anything. I even put on my list when I plan to do something and how long I think it will take. Hope that this helps.

Praying for you.
