Hello and Welcome~~
I'm so sorry that your life is challenged by your health issues. IMHO, your primary doctor is not giving you the service you are paying for. You are asking for help and she blowing you off as if it's all in your head. Your symptoms are very concrete, not imaginary by any means.
First I'd get a referral to a specialist. Most likely a rheumatologist like Sherrine suggested. Then I would highly consider finding a new primary(general) doctor so you are getting treatment with respect. Unfortunately the younger you are when you have chronic pain and other symptoms like yours the harder it is to be taken seriously. Your age groups receives some of the worst medical care when it comes to Chronic Pain and autoimmune symptoms.
I know it's not a fun task but please begin looking into finding a good health care team. One of the best places to go if you have as many individual symptoms as you do it to a teaching/medical university. In the Fibromyalgia 101 thread there's a link to many of them around the world. Here's the link so you don't have to dig for it.
en.wikipedia.org/wiki/List_of_university_hospitalsIt's as easy as calling them and explaining your situation. They can match you to a doctor appropriate for your major symptoms. These folks will not only take you seriously but won't give up. These are the people doing the cutting-edge research so they will keep working until they find some answers. It might be a long drive for you but it will be more than worth it to get this quality of help.
Please stay in touch...
