6 Yr old not in school in MA LONG STORY!!

I'm in a situation where my children(3 of them) and I are staying with my mother in a 2 bedroom. my son who is 6, ik is supposed to be in school. I can't use my mother's address for him because I'm not supposed to be living with her because it's a 2 bedroom(my 14 nephew lives here too) and her landlord & maintenance has heard through the grapevine that I'm here. they'll evict my mom. she is risking all for me. we've dodged them so far so they haven't caught me here. my kids are 2 months, 5 next month, and 6. I can't work because I have no sitter. My mom works 40 hrs a week, is dead exhausted, and is 62 yrs old. Their father who I'm married to doesn't live with us. We moved here from AR because we're originally from here (MA) and our families are here. He lives 30-45 mins away. he finally just started working again after being laid off from his job for a month. he never saved any money for an apartment and when we did have access to money, our credit has been denied everywhere. I've looked into shelters and they'll only help you if you're in danger or have been put out by a fire or natural disaster. he's very controlling. How much trouble am I in? I'm gonna be answering to whomever because he's my son. only stepson to my hua fsband but my son doesn't know that. Now I called my county's public school superintendent. they told me the only way to register him in school is he had to have an address in our county. I explained my situation to her which when I called, it was only like he 6th day into the school yr. I had my 3rd baby on Oct. 5th. 2017. 2 weeks after I asked my husband to rub my shoulders to which he did but unbeknownst to him he had fucking poison ivy on his hands. I'm severely allergic. by that night I'm scratching like mad. thought it was shingles cause I gave that but nope. it was poison ivy. I got covered from the back of my head to my tits. then while dealing with poison ivy, i popped shingles cause I was stressed tf out. I got poison ivy in my armpit and that was it. I went to the ER. They were like whoa! I was a scratching, oozing, mess. they gave me meds and I went home. well a few days after I notice this hardish small knot like ball in my arm pit. it was wicked tender. hurt so bad just by touching. my mom tells me it's an abscess. never having one before I listened to her about putting a hot compress on it. I do. next day there's a white head. I pop it. well way long story short, I had fucking MRSA. I was terrified. I ended up having surgery and they cut my armpit out. I kid you not. I was in the hospital for a week. I'm now healing at home but now I have 2 different strains of staph in the wound. ive been going to their wound center too. on top of all that, they discharged me with instructions on how to care for my wound. well i listened to them and i developed MOLD!!!! in my fucking armpit. SO I'VE BEEN THROUGH EXTREME STRESS. I'm in the middle of another shingles outbreak on my hands now. So there are extenuating circumstances as to why my son isn't in school right now. he just became potty trained 2 weeks ago. my son is on the autism spectrum scale. the dr. said the only way he'll really get help with the Autism is by going through the school who will help him. idfk what to do. I'm so scared. I don't drink. I'm not an addict. how much trouble am I in????
