KA, every person is different. Some people are very private and do not want anyone knowing their business. It is very difficult for such a private person to share any of their business. They might discuss such an illness with only their mother or one other family member or Rebbetzin, someone they can trust NOT to share it with.
Other people, share their pain and emotions with their friends and family so they can offer support and advice. They also can help with research, with the kids or any other areas that a choler can use help. One very important thing is to reach out to Hashem and to strengthen your emunah and bitachon. It is very hard to go through such difficulties if you lose that. The only real way to get through difficult times is to trust in Hashem and be one with him. The truth is you get the most strength from emunah and bitachon.
Also, here at the CR, we are really good at offering support. So at any time, if you need to vent or you need our support, we will be there for you.
