Sleep disorders can cause your symptoms. Talk to your doctor if that's a possibility with you.
Hi
Thanks for writing to the forum!
This could be due to onset of menopause that causes several hormonal changes in the body. In all probability a hormone replacement therapy should help you.
Apart from this eat a nutritious diet rich in fruits and vegetables. Exercise in fresh air.
I would strongly recommend you to see a gynecologist. It is difficult to comment beyond this at this stage. Please let me know if there is any thing else and do keep me posted. Take care!
