I think my cat's tail is broken :(?

I think my cats tail is broken and I dont know what to do. Recently about about half way down his tail it is drooping. also when i put even thelightest amout of pressure on this one spot, it realy hurts. I've read some things that say you should take them to a vet and some say it will heal on its own. If anyone actually knows the answer to this please post a comment. Also, please dont just write something like "that sucks" or "too bad" because I need real answers. I love my cat very much and I dont like to see hime in pain.
