Welcome to FamilyHub - it is lovely to hear from you.
It is wonderful that your husband supports you and your son but is sounds like you have a lot on your plate.
Does Jake get any extra support at school?
Do you have any contact with your local Mencap? There are lots of different groups all over the place - have a look and see if there is anything that appeals near you: https://www.mencap.org.uk/search/groups
If you’d like to talk to someone about how to get a bit more support call our Learning Disability Helpline on 0808 808 1111. Our advisors are available from 9am to 3pm, Monday to Friday.
I really hope this helps and that other parents share their advice on here too.
