Don't worry about it, Jet.
WinXP has been EOS (end of sales) for a long time already, now at EOL (end of life) it simply means that Microsoft won't be issuing patches and updates, nor will they provide technical support or sell new copies. Existing machines will continue to work just as they did before. As long as you haven't lost your license keys, you can even reinstall and download all the patches and updates that were released over it's lifespan as they are not being taken down.
Implications to you in the capacity your home machine is used is probably minimal, if any at all. So if it works for you, there's no reason to upgrade solely based on the EOL announcement.
While Microsoft has dropped support for the machines and is raising the virus/attack/malware panic flags, the reality is that most of those things are being taken care of by your 3rd party firewall, anti-virus and anti-malware programs, which are still being updated as they use the same databases as the versions of those programs that run on the newest OSes. Programs like Avast, AVG, Norton, Malware Bytes, etc. are still going to protect your system
Home and business computers that are on protected networks really aren't at any more risk than they were before. I have seen machines that have had their updates turned off for years and they are running just fine.
Machines that sit exposed on the internet might be in for a bumpy ride though.
