Need advice about changing my major

When I was in middle and high school I was depressed so depressed I wanted to kill myself, but I have overcame that and from to time I will still think about it but not as badly as it use to be. In my senior year in high school people were thinking about which college or university they were going to and I honestly didn't think I was going to make it to college, at first while in college I was undecided then I picked a major based on a personality test, I will be getting my associates but since working at my job I noticed that I really enjoyed working with kids but don't exactly what to study. I thought about teaching but don't know really. Now I'm torn between graphic design and teaching. I don't know what I'm going to study next semester and I forgot to apply for next semester so should I take a semester off, double major in graphic design and teaching, or just pick one. I don't want to waste money and continue to change my mind from one to the next. I would just like some advice please.
