There have, indeed, been some literature linking depression and seizure disorders. However, whether your depression and anxiety is related to the seizure episodes is something that still needs to be determined.
There are other possible causes for your seizures. Since you are in college and are a working student, stress and fatigue can play a role in triggering your attacks. Vitamin and mineral imbalances can also possibly lead to the episodes.
What you need to do is to consult your neurologist, as well as your counselor or psychiatrist, to manage these concomitant conditions.
Hope this helps.
