Feeling empty and demotivated need help

I am not in any clubs cult or tech so I feel like I miss a lot of opportunities and exposure so I feel kind of demotivated. I was in a school focused on academics only , I thought clg life would be different. this feeling is eating me. everyday I go to class and come back to hostel only. I don't have any hobbies and stuff. I even tried for e summit and Ted x interviews but I don't know what they want from me. i tried tech clubs but rejected in last round. I have been rejected like 5 6 times till now.Academics are also not going well i fucked my mte very hard. I know clubs don't matter a lot but I wanted my clg life to be different from my school. I wanted to part of a peer group but now I feel empty what should I do.
