Alcoholism Recovery & Treatment

I am planning to major in Psychology when I transfer and then when I’m done, apply for School Counseling (Grad School). I was given some advice in calling some youth centers, schools, etc and try to find volunteer work. There’s just so many different thing to help in, where would I look into for School Counseling? Would any be beneficial? There’s drug and alcohol abuse, job counseling, education (tutoring etc) all sorts. Any suggestions or advice?
