Be sure you get a deadbolt for every room in the house..... get a smoke alert alarm for every room too...
and any other safety device you can afford ( survillence cameras to watch her, even while she sleeps) in case she goes from suicidal to homocial and decides to crawl into the kitch one night while everyones sleeping and turn on the gas on the stove.... or sneak into someones room at night and hurt them.... maybe not even intentioanlly as she is suicidal, which means she has some severe mental health problems...

or some other such situation you may find yourself in .. as she will most likely do VERY ODD things and quite a few times too !!!. Also if you have pets, get rid of them NOW... as she could slip the dog the pills she decides not to take.... hurting or killing it.

Your going to be sorry for doing this... helping someone as unstable as she sounds... by letting her int your home, and your not trained professionals in medical or mental health... your life is sure going to be chuck full of surprises, most all not good.

I have worked with people like you describe her, the things they can come up with will blow your mind....
as will the trouble they can get into... even though you dont think she is capable because of her being overweight / long time smoker ( guess you mean she has COPD or something like it)
as you said, as she most likely can do more than you think she can.
