Well done trying to put it into words. I can't explain why Thailand is so addictive but it's just so easy to feel at home and you can just do your own thing without hassle and take it however you feel suits you.
You'll be fine at your new location, just a nice local area which has always worked for me.
I do hope you get down to Samui though, straight off the boat and stay at Nathorn on the harbour front where there are the most amazing sunsets and great coffee shops whilst still maintaining the local vibe. Although there are more tourists there than there have ever been, most jump off the boat onto transport and away to the tourist areas but Nathorn, has 500baht a night hotels right on the sea front only 500m from the boat and 7/11s and a small lotus etc, everything you need.
I'm so happy you're feeling peace and contentment , no one can ask for more than that :-)
Take care and stay happy :-)
So far, I am having fun over here. It's just a nice place to be and I am looking forward to try the boats. Today I successfully discover the maze of MRT and BTS alone and survived xD. I'll have to make it to Koh Samui at some point but will see.
