Hay Ewe,
Yes, indeed, very important, get help if you feel your life is not bringing what you are hoping for, or what you feel you need.
I strongly believe many people are scared. The step you need to take, the fear of getting help is still big for many people. A "depression" is in many cases still not accepted as a normal medical problem that needs to be treated. It is usually called a "weakness" of yourself, you, weak person, who can't deal with the problems you're confronted with.
Many people tend to blame themselves, their personality, believing that they, the PERSON they are, cannot live anymore in the world they are living in. I've had a friend who had the same problems, fortunately other friends could make her to take the step and get help. In the end she told me, at first, there's one important lesson to learn: who you are, is most of the time NOT the problem, the problem is usually how you interact with the environment. And by changing the way you interact with the environment, you can achieve a lot. Some problems simply dissapear this way...
I hope this can help some people...
