Anyone else feeling this too?

Hi everyone... I need guidance, please.
You see, I am so tired. I've read in this part of the forum that I'm not the only one... but I just don't know what to do.
To begin with, 2007 was a very hard year for my family and me. My dad's dad passed, the 4 y-old daughter of a close friend, a great-aunt, and in november, my brother's baby (due this month) was stillborn. I was in a relationship, and I had to end it because my couple didn't believe in marriage nor wants to have children before 2012 (and I am 28 already).
Economically, the year was terrible. We didn't even have money to buy christmas presents. I am swarmed with debt, I work for my family's company, but I have taken the decision to get a job elsewhere since we have no money.
I am getting a job interview in 10 days, for a job in another state. I didn't want to go, but the situation with my family is getting complicated, and I haven't found a job here.
My dream has always been to be a full-time lightworker and live of that... but it just hasn't come through... I feel so tired... I don't know what I am supposed to be doing here on Earth... I thought I knew, but every effort just doesn't come to fruition...
Do you feel I will be happy with this new job? Is this the way to go? I feel so down and sad... lost.
Is this just a passing thing? I am so confused... thank you all in advance for your help.
Love,
Aida.
