Did I make a mistake

I moved back to the UK 5 months ago after 7 years in the Bay Area. I left a HHI of $250K and now on £130K combined which I thought would be good but cost of living is so high here it doesn’t go far. My parents constantly talk about how awful the UK is and how everyone wants to leave and that it’s going down the toilet. I came back to be closer to family as we have a 2 year old and I didn’t feel safe putting him in school in USA. He has a place at a fantastic private school here as my husband works there and gets 50% off fees. We just got an offer accepted on a house in Haywards Heath and my mum said it’s a shithole so now I’m spiraling about that. Just worried everyone is leaving the UK and I came back here and taxes are about to go up again and did I do the right thing financially, I don’t want to work until I’m 80. Thanks
