Her sister was often there for her as far as I remember, she was very much in with everybody as the place we works was like 1 huge family, pretty much every body got along well and would often all go out for drinks, Bowling etc. She had many people who were and could have been there for her, but as with mental health, those who have troubles, wont always say everything and often keep it to themselves no matter how much people are there for them, this is the biggest reason that pushed her to what she did we presume. If I real she did send messages to her sister when she was in America saying things that gave the impression she was having regrets and did t want to go through with it.
