Help me and my son to start over

Hi. I am Nimra. I am 30 years old. I'm a doctor from Pakistan. I worked very hard to pass UK liscening exam and started working in A&E in 2017. In 2018, I married a British Pakistani. Soon after our marriage, I realised that it was not a normal marriage. My husband was good to me in front of friends and family but would ignore me when we were alone. His excuse was that he was getting used to having a wife. But about a month into our marriage, I found out that he had HIV. I confronted him and he made up a story of how he got it from Pakistan while having some treatment in the hospital. I believed him and accepted his HIV status. Things started to improve between us after 5 months of our marriage. But then I found out that my husband was a homosexual. Again I confronted him and he begged me to give him a chance. He said he was Bi and was capable of having a normal relationship with me. And that he in not interested in men anymore as he is happy in our marriage. So I forgave him and gave him a chance. After one year, I got pregnant. Things completely change immediately after that. He started ignoring me again. And was always on his phone. I grew suspicious and checked his phone and found out that he was talking to men again. He blamed me for spying on him but did ask for forgiveness and I forgave him again for our child. However, things didn't improve after this. He stopped talking to me. And started to isolate me from my extended family. I was pregnant and hurt and alone but he didn't show any compassion. During my last month of pregnancy, I again read his msgs to men but I was heavily pregnant and had no other option than to stay with him. After my delivery, things took a turn for worse. He started threatening to take my baby away and started being physically violent. I went into depression and told him that I wanted to go to Pakistan to my parents for a while to get better, on which he beat me up and said he'd kill me but would never let my son go with me. I left after talking to my husband to get a break from all this because as a new mother it was very stressful for me and was also affecting my child indirectly, but later, I found out that I have been wrongfully accused of abduction. I asked him to come sort this out with my parents which he refused. He threw all my stuff out from our home and left it outside my uncles house. He also informed the home office that he doesn't want to persue my spouse visa application any longer. And he has also filed a case against me for child abduction. For this reason, I will have to return to UK. But I have no money. Everything I earned before my maternity leave , I paid it towards the home deposit, bills and council tax. I have no home to come back to. I tried to get housing from council but they can only offer me rented accommodation because I haven't been in UK for that long. I can't afford to pay the rent. I also tried getting legal aid to get an occupation order but the lawyers are telling me to pay 3k upfront and I don't have that kind of money saved. I can't afford child care so that I can start working again. I also need to change my visa status which would require money too. My parents are helping me but they can't do much. I really need help just to get back on my feet again. I don't have much to offer except thanks for any help I can get. I would appreciate it alot.
