moving is always stressful, so sorry you have to go through this. Glad you have people right there to help you. Do be sure to ask for help if you feel "stuck" on any project. If you are moving locally, you might not have to have boxes, use plastic trash bags for all the soft stuff such as clothing, towels, blankets... easy to pack around furniture.
Of course certain things that are breakable my still need tlc and protection of being wrapped up and safely stowed in a box. I learned from many many moves over my life time to carry a small box with soap, tP, a couple of towels and some paper towels and cleaning stuff. Put in a set of nice clean sheets for your bed, and bring your pillows with you in the car.
Put the bed into the trailer last,or bring it over in the first haul if you are doing multiple small loads, so it will be the first thing off, and set it up immediately when you get to your new place. ( or have a helper do it!)
That way when you are exhausted and can't do any more you will not have to push yourself to make up the bed and etc before you can sleep.
Towels and soap, cleaning stuff will be right there if you need it as you set up your new household and you won't have to dig for what you need before you are able to use the bathroom, or do dishes.
I survived over 30 moves in my lifetime, I know it is hard right now, but if you look back, you will see that you survived and adjusted, and I bet you do this time, too.
It might seem forever when you are caught in the middle of it all, but this will eventually end and there might be some fun and interesting new things to come out of it all. cheering you on, keep us posted.
