Welcome!
Start working out......
GO BACK to school and get a degree in any field that you have interest in. It doesn't matter subject wise. Think about "what of I can't be a cop" and I have to do something. What would that be? Find a major related to that and get the degree. It will be the best thing for you.
KEEP the miserable job. We have all had them. It pays the bills and you are good at that. Later in like when folks look at your resuem and speak to folks, they will look at your performance, not if liked doing it. Good perfromance is everything.

Hobbies are when you have time...and right now...you shoudl have NONE becuase you shoudl be working, studying or working out. You are You don't say why mom and dad are charging you rent suddenly. I can only infer its cause you stopped school. Sit down and have a talk. This in your plan......school....job....workout....get a job as a _____ once you graduate and possibly pursue a career in law enforceemnt in the long term.
Thats what I think you should do.
-In God we trust. All others, put your hands on the car and don't move.
