I m going to Thailand(Bangkok) for 3 months at 26th of october.I m still thinking..should i go there?

For God Sake, you got over 10 months to think about it. Wait about 7 months than ask. While you're waiting think about what type of visa you plan to stay here with and save a lot of money if you plan to rent a house, since most landlords wants 2 months security deposit and first month rent. Then try to get your security deposit back when you leave.
