**little background*** I lost my full time job 3 weeks ago for a company I worked for for 8 years (new owners, daughter didn't like me, etc) my husband works full time as well. We currently live with my parents and are saving Money to get a place of our own. We have 3 kids ages 1, 5 & 7. The day after I got laid off I got a job offer working for a doctors office. I thought great at first but now that I'm off I have so much more time to study(during nap time, at night, etc) then when I was working full time. I'm currently in ap1 & med term. If I go back to work I know its going to be a struggle again and I'm hoping to get accepted for next spring or fall. If I turn down this job do you think that's a selfish move on my part. I want to get into a program this time (I was denied at the beginning of this year so I'm retaking classes) and get the ball rolling. Please help!
