<human>: Provide a brief overview of the text.

My brother just turned 30 today, and I'm planning a surprise party with all of his friends on Saturay. He has been struggling with depression for about 4 years now (maybe more, but it wasn't diagnosed). I think he might be depressed because he's never been in a relationship with a woman (he's straight), is still in school, and all of his friends are building families and have careers... Nevertheless, I didn't except him to be depressed about turning 30. He's actually been open about talking about what he wanted for his birthday when I asked him before, and didn't seemed phased by turning 30 at all. In fact, he's the type that usually considers his  birthday as just a normal day, but with cake and presents. 

Today, I posted on Facebook about how I was proud and happy to have such an awesome big brother, etc, with pictures of us as kids. After, I sent him a regular ''happy birthday'' on Facebook Messenger. When I got no answer, and saw that he read the message, I jokingly told me that you usually say ''thank you''. He answered me, ''I'm sorry. I'm avoiding Facebook today. Thank you''. Plus, he's been ignoring all birthday messages from our mother (who sent him a message on his cell phone, e-mail address and Facebook Messenger haha...). We all have a good relationship. 

I'm wondering if the surprise party is a good move, in this case? Or will it make things worst?
<bot>: My brother just turned 30 and is depressed about it. I'm wondering if throwing him a surprise party on Saturday is a good move.
