Hi, I'd like to help you with your question.
It sounds like you are trying to adjust to living in a different arrangement than you are used to. That is a hard adjustment. But there are things you can do to make it easier.
Try giving it some time. When something is new and different that we are used to, then your mind takes time to adjust and create new ways of looking at things. Once you become more familiar with your surroundings, things will get easier.
Surround yourself with the familiar. Keep pictures of family and friends nearby and all around your new place. Keep them in your wallet as well. Contact your family and friends often and have them over if possible. Keep things that remind you of good times and people in your life all around your new place. Have familiar objects and comforting things like favorite blankets and trinkets. This will help you feel more relaxed.
Explore your new neighborhood a little at a time. Each day, try a new place. Before you realize it, you will feel at home.
Try relaxation techniques to help you sleep. Here is a link to help you:
Also, consider chamomile tea or another soothing tea at night before you go to bed. Establish a routine so your body knows when to settle down. Don't do anything that will excite you such as exercise, or watching an upsetting show. This will help you wind down and relax so you can sleep.
I hope this helps you,Kate
