Still a work in progress
But so far my current Answer
Tefnut
my father has lost something entirely
As indicated by wikipedia[https://en.wikipedia.org/wiki/Eye_of_Ra#Procreative], After " Shu and Tefnut, the children of this creator god, have drifted away from him in the waters of Nu" Atum/Ra "sends out his Eye to find them. The Eye returns with Shu and Tefnut but is infuriated to see that the creator has developed a new eye, which has taken her place". Thus in losing his original eye (although he generates a new one), he loses the "Eye of Ra". As an alternative explanation, seeing as the previous was weak, instead another variant can be considered, wherein "the Eye goddess becomes upset with Ra and runs away from him." thus in this instance, Ra permanently loses the original eye, and does not claim her by "by giving her an exalted position on his forehead in the form of the uraeus".
I have a granddaughter who knows everything
According to wikipedia[https://en.wikipedia.org/wiki/Isis#Mother_goddess], Isis, Tefnut's grandaughter, "By virtue of her magical knowledge ... was said to be "more clever than a million gods".
The apparatus of conception is what made me grow
According to Wikipedia[https://en.wikipedia.org/wiki/Tefnut#Mythology] Tefnut "is said to produce pure waters from her vagina.". Vaginae being genitalia, the "appartus of conception", and her's able to produce "pure waters" coupled with herself a deity "of moisture, moist air, dew and rain" would, by my inferring from this data, be self-nourished and thus grow.(This isn't based on research but itself is my own inferrance).
What my father has lost, makes him shine
What the Father, Ra, lost, the Eye of Ra, makes him shine. Again consulting wikipedia yields a description of the solar uraeus: " [it] represents the Eye as a dangerous force that encircles the sun god and guards against his enemies, spitting flames like venom.". Note "spitting flams like venom", which as flames produce light, causes "him [to] shine".
i was born in a bubble
According to (wikipedia)[https://en.wikipedia.org/wiki/Tefnut#Mythological_origins], Tefnut arose either from the act of sneezing: "Atum was creative in that he proceeded to sneeze while in Heliopolis. And brother and sister were born - that is Shu and Tefnut" OR being spat out: "In some versions of this myth, Atum also spits out his saliva, which forms the act of procreation. ", which both involve liquids, able to contain of pockets of air, and thus satisfy her being born in a bubble.
and my father has sad origin
Her father Atum-Ra, is said to have "created his children—the first deities, out of loneliness." according to wikipedia[https://en.wikipedia.org/wiki/Atum#Relationship_to_other_gods]
