mentally unhealthy living conditions

my son and I live in a very mentally unhealthy home and not enough money to leave. Long island is so expensive to live and I live with relatives right now. now they are always getting in my business making this parenting 3 person job because they don't trust me with my son because I don't raise him by their views. for the record they don't trust anyone. they constantly expect me to report to them what my son did, what he's eating, when ever he is sick they call the doctor and give false information before I can even contact the doctor. they are always getting on my case about everything I do baby related or not. I am 38+ weeks pregnant expecting any day and my son has croup currently and all I am getting is stress from them because they feel I am not doing everything I can even though I am. I am too far along to be stressed and dealing with a sick 14 month old. I get their need for worry but they never let me be the mother without criticism and I get every mother goes through it but I go through it every day multiple times a day. I tried talking to them and they never listen to a word I say, in fact everyone tried talking to them and they never listen to a word. now I appreciate very much that they let me live with them but I don't feel that doesn't give them a right to passively make me feel like a bad mother every single day of my life. and I know their house their rules but regardless if it's their house or not i dont feel anybody has a right to try to control how someone raises their child. they let me stay here knowing full well I have my own way of doing things they could have said no but they agreed. they constantly assume every aspect of their lives and everyone else's lives and consider it the truth. so even when someone corrects them and tells them the truth it doesn't even matter only their suspicions are correct. so I bet you can imagine how hard th st is to live with. even when I didn't live with them I would constantly get told to not feed him so much breast milk etc.. I wish I could just leave but I don't make enough money to leave as of right now and afford all the expenses having children come with. I can afford my children and I can afford food, water, etc... but I can't afford a place of my own yet. I am saving though but I don't think I'm gonna be able to handle having both my kids here. even my therapist said it's a very unhealthy situation. no hate just needed to vent and possibly get some down to earth advice even if it's not something I want to hear I don't mind honestly
