Hello, I appreciate that you reached out with your concern.
From the information you have given, I'm seeing neurological and psychological issues. It would be better to go for psychometric test to exactly find out whether it is depression or the anxiety. Also because it is since long time, it might be a personality issues. Psychometric tests will help you with the same.
And for the time being just maintain sleep hygiene like sleeping on time, detoxing from screen 2 hours prior to sleep time and practice Yog nidra for insomnia.
