Hello Paige,
Unfortunately, without a bachelor's degree at least, it is difficult to get a paid experience in the sector. Maybe you can look into paid internship opportunities. That is how I made money while studying, though it was for 6 months. There are other jobs that merely require a high school diploma like a receptionist, administrator or secretary job. Maybe you can look at local hospitals with open vacancies in those positions. Other than that, you need at least a bachelor's degree to get an 'actual job' in the psychology field.
All the best,
