Siblings working together issue - Help!!!!!

Hello All,

I am going crazy here ... Here my situation. Maybe you can give me some advice, Please. I graduated this past May. The first time I took my exam I failed but passed on my second try, only with God's help. Now, I have literally been looking for work for some time now since June and have only been told they are only looking for 1-2 yrs experience. Sure everyone has heard that line one time toooooo many.

OK, the two places I do know that's hiring are home visiting agencies. Both of them I faxed my resume but only put that I was looking for part-time work because at that time that's what they were hiring for. But I wasn't considered because I didn't pass my boards yet. Now I called both companies back and they are only hiring full-time. I currently work full-time at a stable non-nursing position.. this is not my dilemma - I am willing to leave my job for nursing.
The issue is .. My sibling works at one of the places I really, so badly want to work at. Another thing is - she is in a position where I would have to explain myself to her sometimes, even when I forget do to something - as new grads sometimes do or is that don't do

I do understand her position in this typed of situation if the two of us are ti work at the same place. sorry I didn't mention that I have only faxed my resume to this company, only after speaking to her about it. And she said "I guess you have to do what you have to do but I don't think it would be a comfortable situation because of my title there."
OK, I'm at the point in job searching where, if this is the one position that I'm offered, I would like to interview and accept it. Keeping in mind what I'm getting myself into but at the same time I would hate myself and I mean really hate myself if I didn't pursue this. (I'm the type of person that if I see something I want, I try my best and everything I got to get. If I get turned down I'll deal with it, but at least I tried.)

I"m a single mom with bills and a mortgage. Leaving my current position would actually be a little drop in pay but managable. I will soon be 6 month without nursing experience and competing with the Dec grads. I didn't put myself though all of this pain, sleepless night, headaches, time lossed my child and stress for in the end, get my license and not do what I so badly want do, work and be a Nurse.

this situation is really hurting my heart because if I can't find anything else so to pass up a position that could been offered because of how my sibling feels about it... I just don't know.

please help me sort this out. sorry if I'm long winded and thoughts are unorganized. I'm confused right now
all of your advice is appreciated

Thanks,
