>>108382Body Dysmorphia is a disorder, and at least 1 in 50 suffer from it. That's a high number actually. Social media and these exaggerated super-models that you see in videogames also makes things worse. You also can't really get over it.
You can only cope.
Some ways to cope with small breasts are: humor [making fun of big breasts], rationalization [reading about big boobs problems], sublimation [adopting small breasts into an idiosyncratic fashion statement], radical acceptance [it is what it is] or reality testing [observing average looking human bodies that don't really have big, firm and round breasts].
I'm sure there are lot of videos on this topic out there that you can watch instead of triggering 40 minute videos about videogame boobies.
