I am hurt my husband didn't respond more lovingly?

I went to the doctor today. I have seizures that I used to be able to control and for some reason for over a year no medicine works. So my doctor wants to have me undergo a 3 day study to see where my seizures originate from. If it is in a part of the brain that can be removed, he wants me to have that part of my brain removed so that I can be seizure free. It sounds good, but still very scary. I'm 35 and have 2 children. My husband is not very supportive. (I often wonder if I have my seizures from being so stressed about our relationship). When I told him, I was very calm. His response was, "Ok. well, thats a lot to process. I'm going to go visit my mom." He left and came back 2 hours later. He told me he was worried about his mom because she was so tired. Then he watched family guy. Later, he kissed me on the forehead and said that he was so happy that there was a cure for me. I said, calmly, "Yup, and all they have to do is remove part of my brain." He laughed and said, well babe I'm going up to bed. I feel like I could have used a support. Am I a baby? Is this more simple than I realize?
