Feeling constantly exhausted

I've been diagnosed with fibromyalgia since April after symptoms started on May 2nd 2019.

I've always had difficulty with sleeping but most of the time woke up feeling okay, like I have had sleep.

For the past month, I've slept for around 7 hours each night although this is usually broken as my fog wakes me up around 34am for the toilet although i go back to sleep.

But i keep waking up feeling like I've had no sleep whatsoever. My eyes sting, I get headaches and just exhausted but I have a whole day of chorse, work at home, look after my dog etc

How can improve this ? I have been to the doctors but they either dismissed me or just tole me to get into s routine.

Edit: * I'm on 120mg duloxetine as I can't take Amitriptyline
