"ESTOY FLIPANDO" IS NOT "I AM FLIPPING"
It is a little difficult to translate the exact idea of "estoy flipando" into English. One of the main problems is that there are probably two versions (an American version and a British version).
The British version is "flipping out". Remember, it is very important to include the preposition "out" because if you just say "I am flipping" that would be a little strange and people would find it difficult to understand, especially because the verb "to flip" means to turn somthing over.
The American version is "I am freaking out".
Hope that helps!
