I was once Bitten by my pet puppy of 16 years back and did not get vaccinated. It was 20 days old puppy. My dog died in 2013. Around a year back I read some news article of a person dying after 25 years of bite. I contacted 15-16 doctors online and had a telephonic call with 3 more. Every  doctor almost assured me that I have nothing to worry at all. Except one, who said , nothing can be done now and he will pray to God that I stay safe. Now the problem is I cannot get over my thoughts. I cannot focus on rest of the doctors advice and getting tensed because of that one answer. What should I do now? I lost interest in everything and is always thinking about that. Please help
