Is there anything stressful going on in your life?
Do you think the stress is the cause of the anxiety?
My baby =(
From experience of other people the thyroid can be affected during times of emotional stress. Do get the tests. If you feel inclined maybe see a body energy healer, maybe an experienced Reiki practitioner in addition who might help with imbalances in your body energy
i've had insomnia all my life. hydrate, get sleep, and know that you'll be getting some good info soon. good luck!
Look up hypothyroidism is my advice on account of your bp and if what you find might apply to you then get a blood test to get your TSH levels checked out. Hopefully that won't be your case.
