Cheer up!
I was expecting some noob to post "Cheer up emo kid!"
But eh I don't see how you can even get Depression. I understand getting sad or upset but depression never really made sence to me, its like it was made up by someone to get attention.
Man, sometimes you are really down. I completely understand. Being an immigrant is hard, I don't have family here, friends nor even my own language here.
What I realize here is that this country really tear people apart. Maybe it is not this country, maybe it is how it works.
I mean, don't get me wrong, I have nothing against this great land, only that life here is different, people are more distant from each other.
Get new friends even maybe a girlfriend, or two. Just don't let it get you.
I agree with VVoltz here for some part. Suicidal rates are higher in countries that have been westernized such as Japan, South Korea, Russia, US and many parts of Europe (with exceptions of course). The thing is that we are not meant to live seperated as VVoltz describes. But that's sadly how our secular culture works. I believe separation is actually a keyword here.
Speaking for myself I am a believer, and by me having faith in a greater purpose of life and a higher will I have been able to cope with most difficulties in life with surprising ease (so far). It is that when you have a hope for something, a dream, and when you are genuinely happy, depression does not easily come to you.
When I was just a few years younger I only lived for the girls and possessions of my life and put all my faith in that they would make me happy. However, they did not. There were good times, sure, but then you could bet on that the bad times would follow in it's wake (girl leaving you, lack of money etc. etc.). Depression, severe or not, would usually come with the "bad times". By me finding back God in my life however I realized how much greater my life could be if I held on to that for which God created us, which is love. And from here on I have enjoyed almost every minute of living, trying to resemble the image of love (God) as described in the bible. Suddenly there was an eternal reason for me to live, something I'd never believed and something I actually had loathed, before. The separation between me and God and between my fellow creature (neighbour) ceased to exist, along with my negative thoughts and depressive nature. Or, you might ironically say that the depressive nature has been depressed, since there is still the monster inside of me.
If you have any interest in knowing the bible at all, I can say that it was the right anti-depressive medicine for me. Don't try understanding it by yourself though! Have bible studies together with (church) people and listen carefully to sermons and you will surely come to know it eventually.
If religion is not "your thing", and you have not the slightest interest in this blessing, my only advice would be to find something greater to hold on to and someone you can talk to confidentially. Earlier someone gave you the advice to talk to people around you about your problems, not only on the Internet, and I would have to agree. Have trust in the ones you love, for most of the time they love you too! ^^
