You do need to look at the other requirements too, and it doesn't sound as though you took up permanent residency for quite some time.
"establish a principal dwelling place in the United States with the intention of permanently residing there, and must thereafter acquire the requisite period of residence before eligibility for naturalization may be established. Accordingly, a commuter resident alien may not apply for naturalization until he or she has actually taken up permanent residence in the United States and until such residence has continued for the required statutory period. Such an applicant bears the burden of providing evidence to that effect."
I sympathise, as my daughter will be in the same situation if she decides to apply for citizenship, as she's currently studying at university in the UK. But the difference with her is that she established residency here first (lived here for well over a year before she left for college), so when she left she already had a residence, bank account, bills, etc. All of her family are here, her home is here, she has a job here that she works in during the holidays, and she has filed taxes ever since she arrived. We've checked with lawyers and they've all said she should be fine, but only because she very firmly established residence before leaving, and because she has no residence elsewhere.
Personally I would suggest you just wait and apply when you're sure you meet the requirements rather than risk it, but your call. Good luck.
