Most people in the UK are not able to make the choice you made.
You might open your mind and consider millions need to earn a living, raise, feed, house and educate their children, millions more are caring for aged parents or dealing with their own health challenges.
The UK is there home, where their lives and responsibilities are.
Your experience of moving across the globe to find somewhere cheap to live is a totally irrelevance to the lives of the vast majority of people in the Uk.
