hi and welcome

the response of the eye,s is one of the few outward signs of injury, slow tracking,with the eye,s is indicative of slow processing and what I term white out moments, and slow verbal response, that causes us social problems , embarrassment, can turn to anger or anxiety at your age, self image is so important and your peers unsympathetic, us older ones , still have issues but maybe thicker skins

the above advice is all good, a second impact can trigger many things, not leased the feelings associated with vicious attack you suffered

believe me ,I know how that kind of thing can effect you

the guys and gurls here will help all we can, but a good nuro psychologist, and maybe some light therapy may help you also, and acknowledge, what you are going through

age is on your side

best wishes
