I really admire how you travel and enjoy your life. I hope I could do the same as well. But i was the type worried too much and need to plan in detail before started my trip, I easily get panic if something out of my plan happen ;( yah.. I know this is bad.. hahahha..
When you do have chance visit malaysia again, please stay for few days. Ask the local bring you enjoy all the delicious food.
