Comfort in a time of great disappointment

The last two days have seen the emotions in my house go from the highest high to the lowest low.  Yesterday, my daughter got a call from a potential employer offering her "conditional employment" based on the completion of both personal and employment background checks.  She was so excited - this is a field she has been wanting to work in for quite some time.  She was going to have to relocate but that was OK because it was an area in Alaska that we had previously looked at living in or near and we really liked it a lot.  Today, the other shoe dropped.  They called her back and withdrew their offer because of a poor decision she had made when working for another employer.  She gave her notice after being accused of improper behavior instead of sticking it out and clearing her name.  As a parent, I tried to advise her of the possible consequences of this decision but it was too late - she had already resigned.  Now that decision has come back to bite her - so to speak.  No only is she not eligible for the position, they advised her she isn't eligible for any position in the field she so badly wanted to work.  I feel so bad for her but I honestly don't know what to do to help.  I can only be here to offer a shoulder and support her in finding a new path to follow.
