Newbie looking to make things better

This is my first post on the network. There are so many of us out there battling with our family and friends. I have been reading lots of threads and feel a little overwhelmed with the whole situation, so here is our story. 

 My wife and best friend, after making it through a really bad run with 3C Ovarian Cancer was in remission for 2 and a half years. The Cancer has returned. We havent started treatment yet, but will soon. I am not sure what is going on with me emotionally right now. My feelings are distant and I have been even told that, "I really just don't even act like I care." I do care! Your never really ready to deal with these sort of things in your life. You just have to do what needs to be done. I do agree with my wife though, maybe I'm not emotionally supporting her the way she needs. Her therapist told her to make a list of what she wants from me. I am hoping that I can find the strength to help her the way she needs me. Its just so hard trying to run a business and be there for her. She says that she feels that she is second to the business. I don't want her to feel that way because I love her most of all in this world. The only way I can stay keep my head together is work and train, its therapy for me. She says i don't ask her how she is doing or how her day is going and she is right! I just want to come home and veg out and sleep. Maybe I need to talk to a professional. One thing I know for sure. We aren't going down without a fight and I will be with her to help any way I can. All the best to the Caregivers and family member that go through this rough ordeal. I dont want an easy life just the strength to endure a this one. Thanks for reading!
