That's where the part about being afraid to be hurt by losing more of her friends and her deep depression come in.

Or as an alternate scenario I could also see this happening:


 * She might also have locked herself in her room and cried over her losses and by the time she came out (or was thrown out due to not paying rent) the others were gone.
 * Now she'd need money desperately to survive, so looking for a job comes before contacting the others. By the time she got a job, she would need to find the others again and by then the insecurities already started to set in beginning the spiral.

Or course this is still vague and unconfirmed as you said and I too hope we'll get more details than we have so far. But if it's revealed bit by bit in the course of the story I will be fine with it. It's most likely a better and less flow-disrupting way to give it out in bits than have one long and boring chapter with all that information bundled together.
