20 Years Old With Hopes & Dreams

Hi! I am 20 years old and I am a college sophomore studying Fashion Merchandising and minoring in dance. I love what I am studying but, I want to get everything done now. With that being said, it seems like everyone my age and under is pregnant or getting married, and I just got into a new relationship almost 3 months ago. I do not understand why I am feeling like this but, seeing people having families and getting married makes me think I am behind?
