You should bear in mind that a lot of people do just the same thing as you, zoom off to Thailand and Asia to escape problems here in the UK. The problem is that for most people, that doesn't make the problems go away. Oh, you get there at first and you're in paradise, new people, places, etc etc.
But unless you speak Thai or Japanese or have a real lucky streak, (judging from your desire to leave due to problems in the UK I gauge you don't) you'll soon see that when you have no marketable skills, therefore no job, therefore a dwindling supply of money, you are presented with a choice: Either settle into a purposeless existence where the sole achievement of your day is measured by how many pints you can drink before going for a slash, or eventually return to the UK. Coming back here means coming back to your problems, which will not have disappeared.
