For the past year I have noticed that my friend is acting quite strangely. She lost quite a lot of weight and missed about 2 months of school due to what she claims to be Glandular Fever. She also goes from being calm and collected to having raging outbursts of temper. She also entered a new relationship with a guy this past year and since then we've grown apart. She says that he has her facebook password to check up on her and seems to be quite controlling. Whenever he's around she drops everything for him and has ditched us on many occasions to stay in with him. What really scares me though is as i was reading through her facebook messages to her boyfriend (she left her page open on my computer) i noticed she was telling how she was vomitting blood and feeling awful due to the cancer. She's never mentioned anything to me about cancer. She also kept sayinghow nobody loves her and nobody wants to look after her. I cant see how she could have cancer as she plays sport regularly and has already booked her college accommodation for after the summer, meaning she must know she'll be better by then. Do you think this is really cancer she has or more of a psycheatric disorder?
