Tortuga, I've read several posts at PsychCentral written by people who have been in your situation. I hope you can connect with someone who has been or is currently where you are.

My sister-in-law (from the US) lived in another country for five years due to her husband's job and she felt just like you did - never really at home or accepted. Like you, she couldn't find a job and she tried several social groups but they just didn't work out due to language/cultural issues. One empathetic neighbor befriended her but that was about it. It was her fantasy to live where they moved but it turned out to be a long five years for her.

(((Hugs))) to you - it is difficult place to be.
