Needing help!

So I hate my living situation, have for a long time. My partner and I live on my parents' property in a flat. My parents and sister live in the house. I've long known I'm an embarrassment to my parents, even more so since losing my job last year (my mum said it was embarrassing and not to tell our extended family). My parents and sister have done so much for my partner, son, and I, but the constant comments are affecting my mental health and have made me suicidal. Comments like "toddler needs to eat chia seeds," "toddler needs a yakult every day,"and "do you play with toddler?"", "toddler shouldn't have x,y,z", "did you pack food for toddler", "you should have dinner ready for when partner comes home", "you should do this", "you shouldn't do that", "if you were renting else where you'd have been kicked out", "if you go to the indoor playground again toddler won't be allowed in the top yard or out the back" etc Constant comments about how my partner, me our parenting, etc For a time there, my sister would yell at me to discipline him as I was getting up to do so. Constant comments about takeaway. I don't drive, and my mum has mentioned that it's getting hard for them to keep driving me and my toddler around. I said that i understood, and it was OK. But her attitude has been kinda shot about it. She gets the shots when we borrow her car, even if she isn't using it. It's the only car outside of my partners that can have a carseat. Like my mental health is awful. Just had an issue with my parents because my Dad was saying that a friend's daughter had saved $300,000 for a house. I said that was a lot, and he asked how much I had saved. I said nothing as I have no income. He said he meant me and my partner together. I asked for them to please stop asking and to stop asking about my partner. We are having issues, and the constant comments and questions are suffocating me. My mum said, "Fine, bye" and kicked my toddler and I out. I'm a mess, can't afford therapy, but I am starting to feel suicidal again. I'm working on learning to drive and get a new job (the latter is hard because every time I try, the suicidal feelings become stronger. I have trauma from my last job) Please help!
