Back/spinal pain

Hi,
Ive been suffering from lower back pain for the past few months, its been getting progressively worse and recently been waking me in the night. Its lumbar sacral area and sometimes thoracic area, accompanied by much stiffness in the mornings which wears off after an hour or two. I also get it when sitting in a slouched position. A warm bath eases it.
Been pretty stressed recently, sharing a house with my ex, we've been trying to sort things out with help of a counsellor, but we are both pretty angry deepdown.Both of us were abandoned by a parent when we were 14, taking our anger at that out on each other.
Scared to move out as I dont earn enough money to support me and our two teenage kids on my own. Feels like Im living with my mother again, she too was bitter and angry and Im feeling trapped and resentful. I feel very lonely, struggling to stop smoking too. Eating much more sweet things and cakes than I used to, for comfort. Struggling energy wise, think my thyroid is out, have put on weight in last year.
I fractured my coxxyx ten years ago, dont know if thats related.
I had eczema type symptoms on my hands and feet last year which responded well to Nat Mur 200
Many thanks
