>>11190I had something similiar, but in my case it was because I grew up very low working class and socially neglected. It felt like it was way easier for my brother to make friends and get through things than it was for me (my female classmates had expensive standards and a certain expectation of etiquette) and I felt a lot of jealousy over it.
That plus being an early bloomer really shut me out of a lot of stuff at the time, though this was a bit before gendie phases became such a common thing.
I do wonder now if being a weeb/fujo helped me through it, though I was still somewhat out of the loop as I couldn't buy merchandise the same way others could. Thank god for pirating.
