I dont think you would find yourself being alone and being alone could make your feelings worse, that said I live in a very very quiet of Phuket very cheap rent (3500 baht ) 2 bed house in kind of a complex of only 4 houses, all the mod cons good internet and cable tv, very safe and secure with excellent naughbours, we have BBQS each month and help each other out when needed but we dont live in each others way, I am around 1 hour from the best beaches and 20 mins to the big shops, it's nice to be alone but also nice knowing I can talk to people when I wont to and in my terms, I am 62 now and felt the same 20 years ago when I left and for me it's the best thing I ever did. No more being screwed by government tax and paying out big for any necessary stuff. If I was you iwould come to Thailand and travel around you would know yourself when you find what you search for as recommendations from others suit others and may not suit you.
