Do I have the right to be upset?

I extremely upset with my husband. I have a seizure disorder and have our whole relationship. He usually takes care of me and our daughter really well. Unfortunately since he got out of the military in April, things have gotten pretty bad. He goes to work and plays video games. He will play for hours. Sometimes up to 12 hours in a day. Last night, I had a seizure while bathing. I thought I was going to drown and it scared me really bad. Thank goodness my one year old was asleep. My husband was in the other room playing his games. My cat was screaming at the door. Once I came to, I started yelling for him to help me since I lose feeling in my arms. I yelled for 20 minutes and he never came. All while my cat is meowing at the door. He was so wrapped up in his game he didn’t help. When I asked him about it, he said that he thought he heard something and was ignoring the cat. Should I be upset? What should I do? I have no family I can talk to you and can’t work with my seizures. Plus we have a one year old and I stay with her.
