SOS Idk what to do!

Ok so I’m supposed to start college in Spring 2019...and I have absolutely no idea of what to study!...I’m really interested in Aviation...But also in Industrial engineering & International Affairs (Diplomacy). My mother hates the idea of me being a Pilot...I wanna be one but I’m not sure...and I would also like the experience of studying Diplomacy in Europe and learning a 3rd language! Or studying engineering in Germany with my cousin!. I’m freaking out! Someone give me a hand here?. I literally can’t talk about this to my parents without bursting into tears because it is so damn stressful I cannot control myself! HELP ME
