Alfreds Medical fundraiser

Alfred is 12 year, He suffers from chronic asthma high allergie level of 486 when should be 0.22, he suffers from pepsin reflux and has a missing piece of his left nose wall will need a major reconstruction,at the moment medical bills medicinces and specialists scans etc cost alot i`m unemployed and my other kids try to help but cant anymore, he now had to be removed from school as he was more at home then school he is starting homeschool with me mom but it also costs but i need my child to be safe and i can keep an eye on him, His father was ordered to pay maintenance but is untraceable so attorneys also trying again money. i stopped working when i fell pregnant with my first child and stayed home for all of them, i was married for 24 years my husband cheated and married a lady while still married to me for 5 years so i got nothing. I have a standard 7 and cant seem to get work also i cant leave Alfred. Any help please this is my last resort and it is so wrong to ask for help. My kids pay for our stay food electricity clothing schooling etc so not much is left for them me as a mother is ashamed, they are big but now my days are to take care of Alfred and thats all that matters. Thank You
