then she can stay with brooke after

but she should to keep up with Brooke

Rachel should, go to rehab and sort herself out. and then come back and stay with Brooke & Peyton.

I agree with what u guys wrote above...If brooke meant what she said to Rachel, she's being unrealistic if she thinks she can nurse an addict back to health by herself. If brooke wants to help rachel at home, she'd better at least hire some professional help so rachel can have round the clock care. Brooke could visit rachel if she were to go to a facility though.

She need to go to rehab, she can come to stay with Brooke after.

idk if my sudden hunch is right, but maybe she took that money to go to rehab. she just had to do it right then and without telling anyone cuz that was the moment she was ready. if she waited, she might chicken out.
