If your mother provided more than 50% of your financial support, then she should claim you as a dependent.
Your income was less than $6300 (your standard deduction), so your taxable income will be zero. By her claiming you, you lose (and she gains) your $4050 personal exemption. But you don't need it.
If all of your income was paid on a W2 (not a 1099), then you do not even need to file, unless you had taxes withheld that you want refunded.
By claiming you as a dependent, your mother would also potentially benefit from one of the Education
Credits.
