Difficulty of a social life in a new country...

I remember all these things in the first year. It's a rough time, but it gets better.

Join some local groups if you can- whatever you enjoy doing and is part of local culture is a good start. It'll help you get a better feel for the culture and help with the language too.

Also, it's not ideal if your goal is to be fully integrated, but I found that having expat friends helps a lot, since they'll often be English speaking and can understand some of the struggles you're going through.

hang in there, it does get better!

Thanks for the optimism I guess i just need a bit more patience.  Expat friends do really help and there are also some great people i met that have been living in sweden for about 5 to 10 years. 
It's very hard getting used to socializing in a new language..
Hope you are right and it gets better.

I can share the same thing here. At least to some extend sometimes I also feel lonely as cannot speak the local language. Thankfully, I have several other expat colleagues where we share the same impression and we try to tackle them together. And couple of my German friends are also very helpful and kindly enough to help us adjust.

But like ECS said, it takes time. I also still trying to enjoy myself dafy after day....try to keep my mind open

Well first would be the hard thing. I mean if your in a distant land, it is hard for the first few weeks or month. But my relatives support me on that times and then as times past by, i gained friends there.
