Help required don’t know where to turn

I’m currently waiting for a diagnosis and have had to come out to work to look after my autistic daughter, every so often throughout my life I either walk out of a job or need a few months away to recharge. The job I do I highly intense and at the moment I can’t see a way back to work, is there any help available as I don’t know how I will survive? Being home is like heaven to me and I want to be here for the kids but in this day and age waiting for a diagnosis is there help availabele
