How do i convince my parents im not depressed?

My parents think that im depressed and i swear that im not. They think that just because i like spending time alone in my room and that im not as loud as them that i am. They all also like to do lots of outdoorsy things like hiking and biking and i dont. Thats another reason that they think im depressed. I just like being by myself and in truth i dont really like them that much. plus, i've already tried just telling them and sitting them down to talk about it but they wont listen. please help!
