Is it normal to be worried about my brother because he literally isn't good at anything?

Anonymous

My baby brother is 21 years old and I'm worried for him. He doesn't work yet, he can't do nothing in life, not even holding a basic conversation for a couple minutes, knowing basic math (adding, division, multiplication and subtraction), boil an egg, barely can take a bus, only knows basic changes if he memorizes the number and he is really weak for a man that can't open a can. The only reason he graduated from HS is because my mother (with help of her friends) used to do all his homeworks for him. He never did a single assignment. He can't even send an email, sign up on any application or do basic computer skills.

This is not for confident boasting purposes but I can literally beat him up if I were a bully and can still beat him at arm wrestling. Obviously given by what I've said he's a virgin but has expressed many times wanting a girlfriend. I'm super worried for him. Is my concern ok?

He can't do anything. We already took him to a psychiatrist and they found no signs of autism. He has a normal, healthy brain. They couldn't find anything wrong with him and even told us that he spoke good with them.
