My colleague tried to suicide?

My colleague 34 y.old woman tried to suicide (by her opinion she meets too many bad people and had enough, but to me she met "too many bad people" because of her bossy but irritating boot-licking personality) but now she is on medicaments and at work she is treated by bosses like a very sensitive untouchable but nice girl because she is workwise is good and fawns on them but I feel she is taking an advantage of her condition and behaves very bossy to others. Now I'm getting in problems with her but bosses protect her. She is manipulative. She was in company for 2 years now, I'm now 1 month. What should I do?
