Depression remedies

I have quite a story to tell you. Read carefully. My mother and father live with each each other as well as me in the same house. Yet my mother has long-term depression and is on almost every anti psychotic, anti depressant thats on the market. Trust me I am a pharmacy technician, interestingly enough. Basically when she was young she had a miscarriage, was raped, parents left her for her “husband”, and she cant seem to move on from the past. The perfect candidate for a depressant according to the books. Now my mother and father are divorced but they have been living together for past 20 years. Its very complicated I know, sorry. She has been getting bad suicidal tendencies, last night she was about to Overdose on her medications, because she could take “life” anymore. Suicidal thoughts are more recurring than ever before. I thought about signing her to a facility for a vacation from work etc. But I don’t think there is an answer to this except live with it, what do you think? Thanks.
