Reconstructing Gothic mythology is harder because we do not have that much sources to go on. Culturally the Goths were descended from Scandinavian tribes and mostly developed as a real culture in the Steppes. I think it is safe to assume that their rituals had the more ''shamanic'' features of Norse mythology and the non-Norse peoples of the Steppes , which seem to not be as pronounced in West Germanic (although it does retain an element of ''shamanic''.
I am getting carried away and please accept my apology for analyzing your faith scientifically.
I do not mean to claim that your faith is untrue, and its message have brought comfort to me. I am just interested in how people historically worshiped the Germanic Gods.
