Hi Monika,
Welcome to the forum.
It must be so hard having your world turned upside down like you have. You’ve come to the right place though. There are quite a few parents here with ASD children so I’m sure many will understand what you are going though and how to help your little lad.
If your having problems with benefits then please call the gingerbread helpline, if you scroll down you’ll find the link for the number. The gingerbread team are trained to help you and will give you the most up to date guidance and advice.
