I am not a fan of Estelle and I really hope, as I have done from Day 1, that Ben wins. However I completely agree with you regarding how she has conducted herself in the face of adversity. Her loved ones must be so proud of her. I think she is a great role model to anyone who sits just left of centre.
For some reason devout Estelle fans find the need to turn her into a victimised little soul who has been bullied to the brink of breakdown, and this simply is not the case. The house is an extraordinary environment. You are stuck with each other 24/7 with no escape. At times Estelle's idiosyncrasies drove the housemates bonkers, and that's okay, as people that happens. From what I have seen, the housemates really seem to like her and they all seem to get on really well as a whole.
