<human>: Condense the text into a few key points

Here's some background information.

-At one point, we dated for a year. Ended on mutual terms.

-Now we are really good friends

I'm not much of a drinker nor is my best friend. But ever since the break up, she has been clubbing hard and drinking a lot. Every night for the last 5 days, she's been out of the apartment drinking and sleeping over other guys houses.

When we hang out to drink, she becomes very carefree and open to do anything.  Like money or her own self-respect  is irrelevant. Which scares me since she's out clubbing a lot.

I'm getting concerned about her health, financial status and life.

 She's  dealing with a liver infection and doesn't take it seriously. Been eating out all the time. She's starting to gain weight and thinks that 10 minutes of minimalistic work outs will lose her weight. She went back home to spend time with her sisters and spent $300 on drinks/food on her credit card (she was drinking a lot). She hasn't put time aside to look for internships or real work. 

I don't want intervene with her actions because she is her own person. But I don't want her life to end up like her siblings: Partying all the time, getting into abusive relationships, pregnancy, in debt, etc. Like she lost a sense of self-respect, responsibility, morals and reality.

 What should I do?
<bot>: Best friend is making really bad decisions when she started to drink more. Don't know if I should intervene or just let it happen.
