Do you have a local childrens centre?
I do and they have been great with the the support they have given me, they have organised counselling for me, and arranged child care with an ofstead registered childminder who picks DS up and drops him off again afterwards, the counselling waiting list was soo much shorted than NHS counselling and the counsellor is fantastic.
They have also arranged for the childminder to take DS for 5 hours every friday so i can have some time to myself, i really value this time as can feel myself winding down from the tension of the week, this has given me the support i need to get myself off of AD's
I also have the support of home start, i have a volunteer come to my house once a week and play with DS whilst i get on with housework, sometimes i just chat to the volunteer, she is so great, i really wouldn't have got through everything without her!
Go to see a different Dr. It is appalling the way they have treated you!
Where do you live? If you lived near me (Stamford) I would help out in anyway i could, even if it was to just play with your children for a bit so you can relax with a cuppa.
I am very sorry for your situation, i wish there was something i could do to help you feel better
