No reason to freak out. Just be patient. Other people's experiences and fast processing times should be encouraging, rather than a reason to go into panic mode. 24 months is the official processing time, and the fact that you are already done with the test so early in the process should be a reason to celebrate. Besides, everyone's process is unique and a multiplicity of factors may either expedite or delayed it, so there is no point in comparing yourself with others.
For instance, your application was received 8 months later than mine, yet you got to write the test before I did. Relax, take a deep breath and be happy to know that you are just weeks away from the Oath Ceremony - two months max. It is around the corner!
