I’m further along into a similar situation, DD 18 was diagnosed first and also has a number of related conditions including adhd
DS 17 was diagnosed with adhd but refuses to be assessed for his quite obvious ASD and is still in denial
DH was the last to be diagnosed with ASD and adhd, they all also have anxiety disorder diagnosed
Although they all have common features they also have differences, both males are sensory seeking whereas DD is extremely sensory defensive and demand avoidant
Counselling is a good idea but really do you work finding the right person, some cause more harm than good
Find yourself an outlet, in all of the madness it’s really really important to care for yourself
I spend a lot of time organising and explaining in very non waffly words why we do or don’t do things, how actions will make others feel and with DH explaining what he needs to do as a father or husband
Like you I have zero support, if I was less unwell myself with a physical illness I would get involved with support groups just to get some interaction with others who ‘get it’
Take care, there are some wonderful days too for families like ours, today our DS’s head teacher complemented us on what a truly lovely lad our son is and how dedicated he’s been to his work through lockdown
