Why am I sad?

I'll confess, I am trying to apply the principles of the Law of Attraction into my life, I've wrote my goals into this blog, I have been reading them, and I was even able to attract an interview to an american company that, at least, would allow me to fullfil one of the goals, the travel part (note: Maybe I shouldn't have defined a goal with the 'at least 1 travel in 5 months', and yes something like '1 travel between 5 months', so I don't know, if they call me, if I'll accept the position).

But, even with that, it isn't easy to forget my current situation in life, I need to admit: I am sad! Do I have reason? Should I really be sad? Maybe don't, but I am, and I need to overcome this sadness somehow, today was especially hard...sad Sunday.

Those are the reasons that are making me sad, I'll write them because I need to put them off...

-> I'm a 25 years old person living with my parents and scared with the possibility of things go wrong when I move to my own apartment

-> I'm a 25 years old person that never had a girlfriend and...

-> I'm really stressed at my job, I want a new one, I know the characteristics of that job, but since I haven't got that "dream job" yet, my actual one is making me very stressed (my right eye is "jumping" almost everyday)

-> I'm scared of all the technology around? Will they replaced us? I can't let that idea go!

-> I feel my life is not moving forward, I'm kinda stucked!

Those are the reasons, I really need to get in a better mood and try to overcome those problems, I really want to believe that the law of attraction is going to help me.
