New job regrets

[user82718199]

I started a new job on Monday, same role as previous job but with a different company. I am really regretting it, I started doubting myself last week and now I'm sure I have made the wrong decision.
Is this normal to have regrets so soon? I thought the first few months would be the honeymoon period.

Every time I have moved jobs I hated the new one instantly and was full of regret. You need to give it a few weeks to find your feet.

The first few months are the worst, IME - imposter syndrome seems to kick in hard! I'd give it 6 months and then reassess.
