What's the Buddhist take on dysfunctional familes?

What would be the Buddhist take on dealing with coming from a dysfunctional family which included physical violence and neglect? It has left me feeling a chronic sense of abandonment, unimportant, low self worth, lack of trust in people or ability to make new friends etc and at times a strong desire of unbecoming. I'm 56 now and started practising insight in my 40s but I still have so much baggage and no real insight into anatta. Im a recluse now and feel like a very hurt lonely person. I get intellectually that there is no solid thing behind all these thoughts and hurt from my past but it still feels very real and very strong and I continue to live as such and act in self protective and defensive ways. Practising has brought me some peace and calm but that's about all. I can't say I feel much joy or happiness in my life. I do practice metta but it just feels forced and fake tbh. I have this very strong urge to isolate myself more and more. I don't like this world or most of the people in it.
