Advice needed

Ju

My best friend thinks he's falling into depression, he's always tired and doesn't find happiness in his favorite hobbies anymore, idk how to help him though it. Ive tried to talk but he's not big on sharing what's on his mind all the time. I've also tried to get him to come over to hang out and distract him but he has no initiative to drive 5 mins to my house and his mom doesn't allow girls over. If anyone has an advice I will gladly accept any, idk what else I can do for him
