Applications & advice

Ok I was let go from my (almost) full-time job about 3 1/2 weeks now. I didd'nt think it would be that hard to find another job (at least part-time or PRN to start). Well, I've applied to at least 10-12 places and only one had called to set up an interview. I did'nt call them back as it was over an hour drive. I thought I'd try to find something closer first. Now I'm thinking maybe I should have, but its been about 2 weeks now. I did hear from a staffing place, but they are out of Florida and I have'nt heard anything since I sent my references and such. Do you guys think I should call and check on any of the applications? I don't like to "bother" people, and I know it takes time to check background and references, but how long do you wait? btw, I do have a part-time job that has been giving me some hours, but not enough. My reg. schedule there is every other Sat. on 2nd, but I've been working 2-3 days a week on 3rd shift. They did say a FT position "may" open up if they can't find an RN, but from what I hear it will most likely be 32 hours a week and I need at least 40 to pay the bills. Now they want me to work this weekend on 3rd and I hate the hours and the drive. I just got approved for unemployment, but the problem is if I work 1 day I only make about $68 and if I work 2 or 3 days, it just gets deducted from my benefits, so I'm basically working for free those days. I did it the past couple weeks, but I just figured out its costing me more to work because of the drive. I don't know what to tell them now. Do you think I should tell them the truth (that I need to work at least 4 days a week so that I'll make more than the unemployment) or should I come up with some excuse? I was kind of hoping that by working and helping them out that maybe I would get offerd full-time or close to it, but who knows how long this will go on. I'm ok right now as I just got my final paycheck from my previous job, but I know the money won't last very long. Any ideas?
