Doesgetting older and going to college and having new experiences get rid of negative thinking?

My only negative thinking is health, and surgical stuff and photos of doctors wearing surgical uniforms... I have repetive thinking about stuff I hear for the first time like endoscopy or catheter or stuff life that... too much thinking that sometime leads to thought of... I dont wanna say it coz the question will be removed, but I'm sure you understand, and if you don't. . your a bitch! Ah jk. .. anyways, will this negative sht go away if I get involved more and step in for life.. im turning 17 in 2 days wich is only 1 year left till being A dog... sorry I meant adult.. IL be honest.. im so wasting my life, that I get surprised when I take pictures or selfie of my self and smile and do weird angles I never done that before, I got way surprised of my face (positive way) this is me telling you how much I sit at home and on my phone and do nothing all day.. I am sure that I do not know what life is other then surgeries.. wich I am not having..
