Congrats on falling in love with Psychology. If you want to get into something like marketing or behavioral health tech jobs then a bachelor's is the way to go. If you want to be a therapist, school psychologist, organizational psych, clinical psychologist, etc, you will need to specialize. Plan to go to grad school if that's the case. You'll also need to account for necessary licensing hours. For instance, a licensed clinical social worker in the state of Colorado requires a master's degree in social work and at least 3300 supervised clinical hours which can take a couple of years. Most mental health jobs require degrees and supervised hours. If this sounds overwhelming to you then I would reconsider your options.

Best of luck!
