@Former-Member,
thanks for sharing so much about your life....you are very open.
It's terrible that so many bad things happened to you. And being abused on online forums... that is very low... that will not happen here. Always report a post by clicking on the 'report post' (or whatever it says) button if that post is abusive. It will be removed. It so rarely happens here, though, as this is such a good community.
I believe the thing about incompetent lawyers... I have had friends say the same thing about them.
Oh well, a lawyer is not your friend, right? They are mainly there for the money... well, that is the impression I get. Some of them may be altruistic, I wouldn't know.
I had an experience with the law due to being unfairly dismissed from my job. It was equal parts fascinating and stressful. In the end, I gave up and did not receive one cent in compensation. I just got on with life.
My friends were a bit indignant, saying "How could you let your employer get away with it?" But the world is a pretty unjust place. I knew the truth of what happened, and that was all that mattered to me, in the end. I didn't want to subject myself to years of battling. Honestly, my employer was dishonest, really crooked, but he knew a lot of people.... including a Q.C.
I'm sorry to hear that your Mum was a narcissist - but I suppose narcissists can't really help themselves, can they? Because they firmly believe that everyone else is at fault? They are stuck, aren't they? I feel for your Mum. It's terrible that people are so unhappy.
My Mum was aways unhappy, angry or completely vacant. Mainly angry! I really could not venture to say what exactly was really wrong with her. But I spent a lot of my time trying to placate her, which made me very anxious, and anyway, it was Mission Impossible.
Sounds like we have a bit in common @Former-Member. 
Your ex-partner was a sociopath- they can be hard to spot. Some of them are very charming.... they sucker you in. You must feel relieved you are rid of him now?
For me, leaving my ex- I was jubilant! It was a feeling of utter relief and joy. I still like to giggle about it... how I just up and left without even a note- like a heroine in a C-grade movie! It was priceless. He took everything, though. Again, I didn't receive a cent (the story of my life?), but I didn't even care.
But even then, I still had my depression and anxiety and panic attacks to deal with and get treated for. It was hard. I struggled on alone for a long time.
