Nothing no one can do, just want to get it off my chest 😭

Im 35 weeks along i really feel like crying because of the situation im going through, my mom kicked me out of her house when i was paying rent, not knowing where i was gonna go and not caring that im pregnant and with my 3 yr old son everyone turned their back on me like it was my fault, im now renting a room but dont feel comfortable the couple i live with,they are always arguing.... i feel useless i would love to work i know i can afford my own place but i feel soo useless cuz i cant do anything at the moment. My friend lives with me at the moment (we share the room) but i feel depressed when shes not here because i dont even feel like going out of the room im tired of hearing arguments all the time so i just leave mostly the whole day....but i havent cried in a while because when i do my son (hes autistic) tells me "mommy no" and gives me his shirt to wipe my face, i just cant help it anymore i feel a reaally big knot down my throat... i dont know what to do i dont feel like im not here mentally i feel like im just living life meaningless 😭💔
