Hi there ~
I understand your concerns. Insomnia
is a very common problem and yours seems to be secondary to sleep apnea
. I am glad you are using the CPAP machine and are on antidepressants. I think that your blood pressure is high due to the reason that you have sleep apnea. I would think, losing weight, exercising and also taking your BP medications regularly will help resolve the issue.
I hope this helps. Take care and have a lovely day!
