Hello keepinggoing247.  You are feeling dazed because a bomb has exploded in your life.........a bomb named cancer.  What you are feeling is absolutely natural.........you would have to be made of stone NOT to feel dazed.  Battling cancer (or watching a loved one battle cancer) is indeed a very lonely experience.  You can be surrounded by sympathetic friends and family members, but at the end of the day, only YOU can walk in YOUR shoes.........and it is hard.  Very hard.  Cancer brings a whole range of thoughts and feelings, it is like being on an emotional roller-coaster.  No matter how much we might  think that we are 'prepared for anything' the reality is that none of us are super-human.  I wish you and your partner good luck on this journey that no-one ever signs up for.  Take care.
