<human>: Can you succinctly summarize the text in 1-3 sentences?

My brother and I go to the same university. Before that I didn't realize he had any major issues. Although I wasn't around when he was in highschool, from my parents, it always sounded like he had a group of friends.
 

Last fall, he started at my university. I attempted to have him join the sports team I am apart of. He had never played before, just like most of the kids that come out. However, he seemed to struggle more to pick it up than others. Eventually, he stopped coming and I saw him very little for the rest o of the year.
 

Fast forward to this summer, my family goes on a trip with a few other families. While there, he is always on his phone. I repeatedly tell him to get off of it and that he's being rude.
 

The next week our parents ask to talk to me. They tell me that my brother has been diagnosed with moderate social anxiety disorder and is seeing a counselor for it. He has been for a while, I had no idea.
 

Then my parents also ask me not to be so hard on him. Apparently, my brother felt I had been too hard on him when he first came out to join my sport team. Which is part of the reason he stopped coming practices, that and the large number of people on the team. He also felt the same when I would tell him to get off of his phone, which I guess acts as his safety blanket. I also chewed him out when he was telling people on the trip that the only thing I do is drink, I drink a lot but its far from the only thing I do.
  
  
He has very few friends and can't deal with large groups well. I want to help him, but don't know how. I used to invite him to concerts and parties but he always turned me down, I didn't know about the anxiety. I used to invite him to various activities. Always turned me down so I stopped trying.
 
 

How can I go about helping him?
<bot>: My brother has debilitating social anxiety. I hope I didn't make it worse, but I definitely haven't helped. What can I do to help him with out being hard on him?
