I Have Been Having Several Issues And I Am Just

I have been having several issues and I am just hoping that its because I am just getting older. I am bothered because I have always been healthy and now it seems as if I am falling apart. I am fifty years old and I really want to know if theses symptoms are things to be concerned with. My husband calls me a blue baby now and I wonder with all that's happening maybe it is in my mind. I was diagnosed hypothyroid about a month ago and I know that it comes with a lot of fatigue but this is ridiculous. It affecting me and my lively hood because I don't have any energy. I can't even work a whole day. I get scard driving home because I am just that tired. I wake up in the morning and my eyes are difficult to open. It takes forever for them to open even after washing my face with cold water. I have been having numbness and tingling in my hands and legs not sure at all whats that about and last but not least I have had 2 seizures and I never ever had one of those before. I sound crazy don't I ??? I am really worried and I am becoming depressed because all these things are happening and I know I can't continue like this. Please help me to understand whats happening.
