Do you have the opportunity to talk to anyone about your anxiety? Do you have a Dr supporting you? Do your family know what you are experiencing?
If you have a look on the Beyond Blue website, there is information there about how to get help and about anxiety as well. You may find some of that helpful.
It sounds weird, but if you look up "Sleep Hygiene" on the internet, you will find different strategies that are supposed to help with sleeping.
Would you find it beneficial to write down what you are feeling anxious about hours before bed time or do you think that might just trigger more thoughts for you?
The more I learn about my mental health issues the better I deal with it...most days!
A psychologist told me to try to accept the bad days for what they are and move on when I am able to.
Thanks for sharing your experiences here. Sorry to read your anxiety is affecting your sleep so much. Hopefully you can find ways to reduce the anxiety and to sleep better.
