Throwing in the towel...

It's been six months since we got our new family member.  However, it is apparent that she may not want to be a part of our family.  She attacks me often and especially in the middle of the night when I go to the bathroom.  I have scratches and bruises from her clawing and biting me. I have to wear long sleeves so my arms are covered.  She has no problem with J for the most part.  We've tried giving her time outs when she acts out.  It's sort of like a temper tantrum.  When she doesn't get her way, she goes nuts.  I brought her in to the vet today.  They couldn't even do a blood test on her.  She went crazy.  The vet suggested sedating her for the blood test.  Unfortunately, that was going to add to the bill which we just can't afford.  She also suggested a behaviorist.  Another way too expensive option for us.  Honestly, I don't think she has any medical issues.  The vet mentioned that she was possibly a feral cat that someone took in at one point.  I really see the only option right now is to find her a new home but who can handle her?  We are considering finding a farm for her to live on.  This way, she can run around outside and I think she'd be very happy.  It still makes me sad that this didn't work out.
