Hi, so my friend has been diagnosed with Bipolar disorder and started therapy and medication.. all was going so well until she decided to stop the treatment for no reason. Since then she has been getting extreme high and low episodes, and they told her to stop coming to work. Any advice how can I help her? She is basically destroying her life and career (She's a Professor at college) and is mentally so down. 

I've been visiting her daily at her house or invite her to mine, and her family never leaves her alone at home unsupervised. Whenever I meet her I try to do fun activities she likes or so. But sometime she would out of nowhere burst and cry. Other times she would suggest something so dangerous.
