Where you want to file should depend on where you plan to do most of your sales, and to a lesser extent where your competitors would likely do most of their sales....not where you live.
The best course of action you can take depends on various factors including your budget, the market opportunity present, etcetera...so its hard to really get into that. However, assuming that your invention is still patentable in the US (less than a year since public disclosure and/or the filing of a foreign patent app or the equivalent), it would initially sound to me that obtaining a US patent would be a priority for you. It is at least possible that you would have been better served filing for a US patent than for a Phillippines patent from the get go.
