I’ve already posted on a few different subreddits and haven’t had any luck. I have no idea what to do or how I can help my sister. 

My sister is a recovering drug addict (she’s been clean from heroin for six years) and currently an alcoholic. She was also diagnosed with bipolar 1 a few years ago. 

She recently found out that her husband of 3 years has been having an affair since December. She’s been staying at our mothers house (yes, I still live at home). 

She’s been drinking pretty much since she’s been here and has been working through a 24 pack of Heineken today. 

She’s been nonstop since she woke up this morning. She made a big breakfast for us all, she cleaned the entire house, tuned the piano, then did work out back in the garden. 

This is really what concerns me the most. She’s also pretty much been stalking her husband. They’re dog has medical issues so they have one of those dog cameras in their house so they can check up on her when they’re out. She’s been checking the camera to what her husband has been doing since she left him. 

I’m also certain she hasn’t been taking her medication. I went through her things and couldn’t find any of her meds so I don’t think she brought them when she left her house. 

I have no idea what I should do. My mom has told me to just leave her alone, she’s coping in her own way. I’m just worried that things might progress and she may end up hurting herself or someone else. She’s done a lot of work to turn her life around and I’d hate for her to throw it all way.
