Based off the first two symptoms I had wondered if maybe you should see a chiropractor for a neck adjustment and maybe some muscle work. Sometimes, something as simple as that can really help! Especially when it comes to migraines. Depending on the root cause, it can also cause lightheaded-ness.

The last three sound like a vitamin/mineral deficiency if i'm to speak on physiological health terms. Maybe a multivitamin and a vitamin D supplement would help? Most people are vitamin D deficient at the very least. Sometimes, if needed nutrients are missing they can manifest as headaches, lack of energy, abnormal sleep patterns and muscle aches (not all from one particular deficiency).
If i'm to speak to more mental health terms, most of the symptoms mentioned can be physical manifestations of depression. That being said, I believe you said your daughter was also unwell with similar symptoms? In witch case I would potentially rule this one out.

Maybe one of these may help as well?
