I need help

I'm a 46 year old woman with chronic pain in my legs and sore joints. I have a terrible memory, even finding it hard to find the right words to use while in mid sentence. I'm extremely tired at all times, so finding my job hard to deal with. My eyes have deteriated over the past three years. I have had a thyroidectomy and am currently going through the menopause. All of these symptoms have been put down to, being over weight, my age, my thyroid and the menopause. Does any of these symptoms sound familiar to anyone, I can't keep going on like this..
