why is it that some people can have 10 concussions and be knocked out for even longer then me and there back to normal within a week or two. and i only got one concussion my life life and now have pcs

what is actually wrong with our brains that creates pcs?

i felt normal a whole month after my concussion and then all of a sudden pcs appeared

i get frustrated frequently just thinking how most people can go on with there life and nothing changes and then others such as myself have to suffer everyday and have a complete life change. everything i used to do is 10 times harder, even everyday chores such as making my bed
