What's my religion? 

It sounds to me like you are drawn to elements of various different belief systems, rather than one specific religion. I know that might not help your quest for a specific branch of paganism to "belong" to, but actually it makes a lot of sense to not put labels on this type of spirituality.

Firstly, many Wiccans and Pagans believe that it is entirely possible to subscribe to other religions as well as their own beliefs.

Also, elements of older theologies are always present in more modern religions. Even some interpretations of modern Christianity still contain elements of pagan rituals.

The faeries aspect of your beliefs is probably the most distinguishing though.

One of the earliest known mentions of faeries can be traced to the Ancient Greek poet Homer, who wrote the following lines in his epic poem The Iliad (translated)

"Where round the bed, whence Achelous springs,
That wat'ry Fairies dance in mazy rings."
(Iliad, B. Xxiv. 617.)Ancient Greeks believed in the existence of sprites and nymphs, and this spread through Western Europe as the Greek and Roman Empires expanded.

Interestingly, one part of the world that remained unconquered by both the Greeks and Romans is Hibernia (modern day Ireland), which has a strong link to Celtic Polytheism/Paganism - a branch of paganism that emerged and thrived during the Iron Age (roughly between 500 BCE and 500 CE).

It is this branch of paganism that I think may be of interest to you as, Celtic paganism developed in the relatively insular Irish culture, and most of the faerie folklore you hear about from the "emerald isle" can be attributed to "ancient Celtic sacro-magical tradition".

My suggestion would be to read a bit more into that, and see if any of it strikes a chord.

I found this article called  The Irish Faery Tradition and the Living Land quite interesting.

On the other side of things though, I am personally quite scientifically minded, and am naturally skeptical about theologies that have no scientific or factual basis.

Although the notion of faeries might seem romantic and appealing, I personally struggle to accept the idea that they are anything more than mythological personifications of nature and its mysteries.

I'd happy to be proven wrong though, so feel free to share your point of view too!
