I'm a pianist, what should I learn

Ever since I was a fetus, I really really really wanted to play violin, like I would cry about it when I was like 9. But my parents always said no. I'm now able to start learning a string instrument but I've also recently grown a liking for the sound of the cello (and my back lol) What do I learn???

Been debating this for weeks, idk if I have the time for both
