Should I quit competitive swimming in my junior year

Swimming just takes up so much of my time. Four hours a day are just spent on going back and forth to practice, eating, and washing up. I am good enough to probably end up making the states cut this year, but I highly doubt I will be able to go for nationals. I feel like I have a talent in chemistry and wasting that time for probably not even getting the national cut when I could go far in usnco or research something of the like with chemistry just feels so wrong. For context, I have been varsity in my freshman year, and am on the road to varsity this year. I self studied AP chem in my freshman summer, and currently am studying for usnco (passing locals is very questionable this year)
