How to move past a bad decision?

[Hushabusha]

Before lockdown began I was offered a job which wasn't perfect for me. Now that things have changed due to lockdown/family circumstances that job would be perfect. And due to these circumstances I can't really get another job - think limited childcare, other jobs potentially too far away to sync with child care hours / no long term prospects now that would have existed before.
I spoke to the company again but they have employed someone else now so it's definitely gone.
I'm now going over it in my head and thinking how stupid I was. If I had been offered it even three weeks later I would have jumped at it.
Any advice to help me move on? I'm trying to think "it wasn't meant to be, there's something better" but I don't think there is something better!!!

You made the best decision you could based on the information you had at the time.

There is no way you could have known the world was about to go tits up so don't beat yourself up.

You've expressed interest to the company and if something becomes available they know you're interested. All you can do is be proactive with your job search. Who knows what is next? I hope it is something even better

You could not have predicted this outcome. Be gentle with yourself. This is difficult because of how horrible things are right now, but they will get better. You will find a good job again.

That wasn't a bad decision,
It was a good decision with a bad outcome (like which college my DD1 went to...).

Thank you all. There's some good advice in there and good mantras to tell my mind - it was a good decision with a bad outcome. It was the right decision at the time with the information I had available. I couldn't have predicted the outcome.
Thank you 😊
