Need some advice

My wife and I are sitting here at the hospital ER with our 20yr old daughter after we recieved a call from her boyfriend saying she tried to overdose on her medications. Of the several she takes I know of 3. Buspirone, lamotrigine, levothyroxin. She's diagnosed bipolar for nearly 2 years, has had hasimodo's hypothyroidism since she was 7. Boyfriend said she swallowed all three of the above medications each in a 90 day supply.

Our family has had a rough past couple of years, I nearly died in a work place accident, I'm 2021, daughter had a large grapefruit sized tumor removed off her neck that fall, my mom was hospitalized in a coma 2weeks before Christmas, my dad was in a serious accident and nearly died. I've been diagnosed with pts, severe anxiety, and antisocial disorder, insomnia, and a host of other issues. I'm on several psych meds for my issues, and I've thought about doing it myself, but never thought about it more than it being an afterthought.

Her nurse says she seems remorseful, but I'm not sure. Where do my wife and I go from here? Do we leave her to her own devices? Do we try to keep watch over her? Is this a cry for help/attention?
