Hi Netdog and welcome to BB forums
We'd love to know more about you, please share if you're willing.
I'll be honest and say it's no surprise that you're finding things difficult! Drought, fire, now covid and the unusual occupation of home schooling is maybe what some people could experience over the span of a lifetime, not in 6 months. It's a huge impact by anyone's measure.
You have the forums here to let out any thing, any time.
I highly recommend the 24/7 helplines.
You mentioned previous MH concerns. Do you have ongoing support there?
Now would be the perfect time to have a telehealth appointment with your GP to talk about your feelings.
You may get a Mental Health Care Plan and referral to a counsellor. Most of these appts are over the phone now for a while. Good and bad for you I suppose?
If you can dip into the Wellbeing forum and have a look at self-care, I think you need some of that.
Alternatively, as restrictions are lifted, you could think of taking your daughter to visit family or friends.
It doesn't matter where she does her schooling as long as she does it all, right?
If you are unable to lend a hand on the farm anyway then a few days away might help.
Even knowing we have choices can lighten our mood somewhat.
