There are many possibilities in the helping profession, and my advice to you is to study and learn and get experience while being properly supervised by those who have greater experience helping.

A desire to help others is a wonderful thing. It doesn't matter what your age is. But it's important to understand that sometimes helping has negative consequences for people, and sometimes it's the helper who goes awry, not the person needing help. Volunteer in your community with a nonprofit organization to increase your knowledge about helping.
