What are the long term effects of electrocution? Please tell me.?

I got electrocuted when I was young. I guess that was 9 years ago. An open wire, connected directly from a 220v voltage source, got stuck on my finger which caused it to burn my skin and my flesh. It took more or less a minute before I was able to pull the wire off from my finger. I was lucky to survive but I didn't go to see a doctor because I thought I was okay. But as my age comes, I noticed some abnormalities in me. Aside from the scars I had from burning, I felt some changes. I could see clearly at daytime, but I get blind at night (when light is limited). I get nauseous and afraid when I step down from stairs when it's dim. My friends also noticed that I don't have tingles anymore. My memory became poor and it's hard for me to focus. Most of my reactions are delayed. Please explain to me what's happening. Thanks.
