You are allowed to feel how you feel.
Exactly this.
Everyone's situation is so individual. I'm a single parent of 3 children working f/t from home in a busy role. I have no support, my children's father has popped up occasionally but mostly not, and has been zero help in terms of the practicalities around Covid restrictions (shopping, home-schooling), and used it as a way to be even more abusive.
If I try & describe this to my family, they are like 🤷🏻♀️ 'he's always like this', like what am I going on about. So I don't bother saying.
But - on my good days I feel great - eg kids in good form, work going well, getting some exercise.
Then I'll have a day where it all seems impossible & I'll feel utterly broken.
I've realised people don't get it. Of my immediate team that I manage, and the wider team in which I work, people don't get it. I hear people with partners at home, some who don't work, or who work part-time, talking about how stressful it is & I think 'whaaat?'
But then I realise, it is, for them. And I shouldn't judge (tho I really wish they would have a bit of sensitivity not to go on about it to me!)
You are absolutely having a tough time. It's ok to have all those thoughts - I get it, you end up feeling guilty that you're thinking like that, but it's ok. You're doing the best you can
