I have fairly fragile mental health (medicated for GAD with bouts of depression) at the best of times, and I was very concerned about how this was going to go. But I've been pleasantly surprised.
My husband and I are getting on well, with him not working or out at activities constantly, all the kids'activities etc we're managing to spend time together and relax a bit rather than constantly being rushing and catching five minutes here and there. I'm still working so I'm out three days a week which means he's been able to get him and the kids in a routine for school and his WFH (teacher).
I have fibromyalgia so the lessened pressure on me to get to work and back, do the school run twice a day and walk the dog has been wonderful.
We've been doing a weekly zoom quiz with my cousins and their partners and our mums (three sisters) and it helps give us all something to laugh about and plan (we're taking turns to host) and gives us that bit of contact.
We also are very lucky to have a large garden so we can throw the kids out into that and all get some space and fresh air when we start getting fractious.
I miss my mum, who I would normally see a couple of times a week. And my friends, I've had to cancel a trip to visit my oldest friend during all this which was awful, but overall I'm doing far better than I expected I would.
I hope you can find some things to help you keep going
