Having a purpose and goals in life is a good thing. Please keep thinking along those lines, even though your purpose and goals may evolve over time as you get more schooling under your belt.
Have you been able to take any Psychology classes yet? That is a good way to start to get a feel for whether you enjoy the field and to help in your decisions on your goals in the next few years. When I give advice to folks who are interested in going into Medicine or EMS, one of my main points is that they should try to find some volunteer or other work where they can start to get some "patient contacts" to see if they enjoy those contacts with people. It would make no sense to have a goal of going to medical school to become a doctor, when you finally start seeing patients and discover you don't like it. For myself, I had plenty of exposure with basic patient contacts as a volunteer in high school and in my early engineering jobs (on my company Emergency Response Teams, etc.). When I started working part-time in EMS, I found I really enjoyed working with my patients, even ones who were badly injured or very ill. I like being able to use my skills to make a positive difference in their lives and well-being.
So similarly I would recommend you look into finding ways you can volunteer with different counseling services (assuming you are old enough to do that volunteer work), so you can start to see what kind of "patient contacts" a Psychologist routinely has. My daughter-in-law is a practicing Psychologist, and she is very caring and amazing. The work can be stressful at times, but I know that her work is important to her and she cares a lot about her patients.
Keep setting those goals, and try to get practical experience as you pursue them.
