my mouse is broken, is there a fix or should I get a new one

[fuknspun]

Basically my left mouse button is broken, it keeps double clicking even though I only click once, it gets very annoying when i try to mark text or move files via drag and drop
is there a fix for that or should I just buy a new one?
If I'll buy a new one, which one should I get? My keyboard, mouse mat etc are from razer
