I'm 53 Years Old And I'm Finding I'm Extremely Tired

I'm 53 years old and I'm finding I'm extremely tired and achy all the time. It takes all the energy I have just to drag myself around. I often have leg pain during the night. It's all getting on my nerves because I want to get in the garden and tidy it up and do other things but I just feel exhausted.mi know I may be peri menopausal but what can I do to help myself. Many thanks in anticipation. Adelle.
