I actually get this, I don't drink alcohol but the need to escape definitely.
I actually went on part one of a 6 week course today for parents/ carers of children with additional needs. We spoke about this, and I am going to say to go to your GP if you feel like this, BUT my lived experience is you go to the gp. You tell them your struggling and they just throw pills at you 🙄.
If you want that take them, for me I have taken them and they don't help me personally. But I do know people who take them and they seem to work for them. Having a neurodiverse child is hard........ try and find local workshops/ courses/ support groups for parents of neurodiverse/ additional needs children.
One thing also from today was what do you do for yourself that you enjoy....... there was 4 of us there, and you know not one of us could think of anything we do just for us. And until your asked that question you don't even realise that you don't do anything you enjoy, as your life is taking care of the child(ren) and/or husband.
So another suggestion I have is to speak to your husband. Hopefully you guys can sort some time where he can be at home with your son and you can do something for you..... go for a walk, get your nails done, do a knitting or crafts class, go out with friends once a month for lunch/ dinner, or get unapologetically wasted once a month. Whatever you can think that if you had the time/ chance to do, honestly try and do it.
Then atleast on the particularly hard days at home, you have something to look forward to
