need a part time job

Everyone has skills.
Think about what you are good at, and what you want to do for a job / career.
Google that job, eg: Engineer, and look at job descriptions for the career.
<The job descriptions will list skills that are required for the roles.>
Then google those skills and do free courses on Coursera or UDemy to get your qualifications up.
Apply for the jobs, and demonstrate you have the skills required.

Try fast food places such as mcdonalds. They take on a lot of students.

And if i've tried that?

Restaurants and cafes also take on students.

we can only advise what to do. there is no 'hand holding' through interviews or doing things on your behalf.

any local or small businesses without websities usually need help. literally go to your local pub ask if you can wait tables, ask voluteering centres and charity shops for a job rather than to volunteer, good luck!
