She hasn't changed one bit
I know this is a reality show, so a lot of what is going on is probably not real anyway, but from what is being shown, it doesn't appear that she has changed at all. She still doesn't respect anyone else. She still can't keep commitments. She can't show up on time. It's all about Lindsay and only about Lindsay. She can't even give her personal assistant 10 minutes a day without resenting him asking for the time. She has at least a dozen people in the apartment helping her, but she isn't the least bit grateful.
It's pretty bad when her sober coach can't say with any confidence that she is keeping sober.
Lindsay definitely is using the whole "I need time for me" bit to her advantage. I can see her whining about being too stressed and pressured to shoot for the entire run of this show.
Oh and btw Lindsay….your little female assistant is going to run off with half your clothes. She is already holding them up to see which ones fit her.
