Is my life over

I’m 19 and too excited to be pregnant with my first born, I still plan to go to college and become a teacher etc! I’ve just been thinking so much lately like after I have my baby is my life over ? I know raising a baby is hell hard of a job to do but to the moms out there did everything change for you? How did you cope with becoming a parent. I’m hearing stories of the dread that comes with being a parent and I’m still so young with so much I want to do and I don’t wanna think that having a baby would slow me down because it gives me more motivation .
