Dismissing doctors: How do you find a doctor who can help?

I have had chronic pain since 10 plus years, I’m 34 now a mother to a 4 year old and life is getting harder day by day
Ana titer positive
D dimer high
All autoimmune panels negative
No other signs of inflammation
But when doctors examine they can feel the muscles are stiff, contracted, rigid.
They think it’s fibromyalgia but nothing has helped me. Since the past 6 years I’ve been on different medicine, therapies everything.
Every other month a new symptom appears and now I don’t know what to do.
Left thigh is the oldest problem, I have sore rigid muscles and I don’t even know what relaxed muscles feel like.
Some doctors think it’s some autoimmune but are unsure.
My new symptoms in the last 2 months
Extreme anxiety/over eating a lot due to anxiety
Insomnia very recent cannot sleep at all
Contracted muscles/ rigid muscles all the time unintentionally I try to realease as soon as I realize they are contracted
Forgetfulness - forgotten a lot of important times of my school/college life
Brain fog
Sleep talking very recent
Pain in my left knee
As soon as I wake up an put my feet on the ground they feel extremely sore.
My neck is tilted to the left side all the time because of extreme pain
In the past I have had high crp
But not anymore.
Can someone please help me.
I can’t function most days
