Sounds like you made a logical and wise decision not to try for that job. No need to question it. And gosh I know people who don't worry if they have no interviews for a month, let alone a week. I know it's not easy but as you say, you want something for the long-term and thus trying for any job that comes along may not be the best decision. But it's so difficult right now because you are suffering from losing your job and from financial pressure that it's hard to trust your instincts. Hang in there - I do believe you will find something worthy.
