Autism

Explanation:

Autism is a condition that has a spectrum, so just because two people have autism, does not mean that they have the same challenges. Some challenges may include behavior, intellect, or even communication. Autism must be medically diagnosed.

Autism is a condition that cannot be "cured" however with therapy and some medication it can allow for the person to communicate effectively.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.
