where in thailand are you staying? i have problems in thailand too in certain places, the english isnt too great in thailand
when you get to malaysia (if you do) youll have people chat away to you. whenver i go there i meet many people at random times!! the thing to do to meet locals and tourists is to go to the travellers bars (sometimes below dorms), some bars are full of foreign people but a few ive been to have nice locals in them too, trying to meet foreigners and share their knowledge.
last year i met some lovely locals in a bar in KL that took me and this dutch traveller outside of KL and around many things for a few days. ive also met travellers with a free itinerary that have ended up coming along with me where ever i am headed.
i am sure youll find people at some point - i have always been a lone traveller and sometimes it does get lonley, especially in places where english is very limited, but these are the times i find i reflect and think about things more - i like to travel and have fun but also learn and find out more aoubt things. it will all make sense soon enough - its daunting at first but everything makes sense after a while!
have fun!!
