Hi Steve,
Focus my son.
You look the wrong way.
You should be thinking of the happy times you had then, not the miserable times now.
You KNOW you will be back. That is more than most 'normal' people will get.
Do what I do.
Whenever you feel down, just try to think of THREE things (picture them in your mind) that made you really happy in Thailand, whatever it is.
Then realise you are LUCKY.
Then,
Take a quick 5 minute toilet break and toss yourself off
This helps me through the day :o :o :o
