Need Help Making The Right Decision

I really need some help making the right decison. I'm working towards getting my RN license, but I'm torn between going into LVN school this February. I STILL haven't even finished my pre nursing classes, so i would be able to apply to the RN program in Fall of 2008. The LVN program is an 18 month program and I could start working right away. I'm a single mom of five. I really had eight children, but three are all grown up. I just got my CNA certification and i can't seem to find a job with that. i have not been working at all for two years, things have been pretty tight for us. I feel like crap when I know that my car will probably be gone in the next couple of days, because I couldn't afford to make the payment. I had enough money to keep the rent and all other important bills. I feel like such a failure. My kids will probably not have Christmas this year. I did go on some interviews and one job hired me, but since I was related to someone that works for them they turned away and didn't hire me. I really need to make good solid choices in the next few months. I know this might sound so irresponsible of me to let things go this far, but believe me I feel bad for all that has happen in my life. My schooling RN schooling is paid for, but the LVN will have to come out of my pocket. I have always wanted to be a Nurse professional. I love this career. I just need to make the decision on weather I should just take the LVN route and start working for my family. Please give me some feed back please. I take the ATI-TEAS on December 18th for the LVN. I know i will get in. My nursing director said that if I go the LVN to RN route that will only cut off two quarters for my RN. I also heard that once I get my LVN I might be able to clep the NCLEX. Clep meaning testing out of it to get my RN license. Help me !!!!
