Any Club or Group for Men (over 30s) to hangout or chill ?

M 33 married working professional. As we grow older we start loosing friends. All my Friends are too busy in their lives & we hardly meet once or twice a year. As I was dealing with stress and anxiety my doctor suggested to meet atleast 5 Friends every month. But I have only 2-3 whom I can call anytime & they are living in different parts of the world. Am I alone or there are people like me who are struggling to make new friends and miss active social life ?
