I can understand your frustration. It's not easy to move back in with your parents.

I would take the time to focus on stress reducing techniques, like relaxation and breathing exercises to help with the anxiety, making it easier to fall asleep. This will give you tools to use when you feel ready to move back out on you own. I use apps on my phone, Relax and Buddhify, but there are many other formats. YouTube has many videos for relaxation. Work on building your skills and I think that you will be fine.
