worried much

Today Im going straight to the point. He had 4 seizures already. That's only just today. He's in the hospital now. My parents just took him. I'm really worried about him. I've got to admit, I'm scared too. I don't know what to do. I try to help as best as I can. I tried to research about it online. The internet didn't really help much. Can someone help me? I feel hopeless here. Really tho, I just want to talk to someone about it. It's too personal tho, so I prolly won't. I'm scared for him, you guys. I really really really am. Even though he's weird, annoying, and acts like a little kid, he's still my brother and I love him. I don't want to lose him. What's there to do but hope...
