It is very frustrating, there is no two ways about it.
For me, I kind of gave myself “off” the time I knew I’d be out of action for - at the time I applied it was around 6 months. So during the days, relaxing, nurturing some hobbies (language learning, exercising, exploring my new city, catching up on tv i hadn’t had time for the last couple of years), I joined some clubs (made a couple friends), made a real effort to get to know my wife’s friends, embraced doing household stuff to support my wife while she works. Do you drive? That was massive for my autonomy - I live in a very walkable area but even so - it has given me so much freedom.
Even with all that stuff it gets boring eventually. I started getting antsy at the end of the 6 months I’d originally given myself. In think my wife saw this so we took a little staycation and then since getting back I have spent time thinking about getting back to work, updating resume, and being a bit grumpy. EAD/AoS comes for everyone eventually but I fully sympathise that the intervening period is a challenge. You’ll get there
