Help me figure out my future?

I just got my ged in my late thirties. I signed up for human services because I want to help people. But now my new school is saying I need to choose between addiction or social work. Now I am confused because I do have a soft spot for addiction but I don't see it as full time. I want to have options in case I get burned out. I have always helped others. Looking back at my yearbooks so many said thank you for helping me. Back then I thought I'd be a nurse. But I can't do vomit or blood so I'd be no good there. I watched a video about getting a degree fast at WGU and I don't know I'm just confused!
