NAB3. You need to get access to the local Mental Heath Team. They are the people with all the resources. Please go see a different GP and ask to be refered.
I did, was assessed and within two weeks was seeing a consultant, had my AD's changed to more apporpraiate ones, prescribes sleeping tablets and CBT. I see the consultant every 2 weeks and the nurse comes to my home once a week, when my boys are asleep.
I was also given 24/7 access to the crisis team as I was in a very bad place.
Please seek some alternative help you are worth it, maybe a differnt GP will make a difference
