people think because I'm 18 almost 19 I'm stupid and don't know anything... I know alot I'm not saying I know everything because I don't. but I do know alot for my age (health wise) because of everything I've had to deal with.. I spent half of my childhood at the hospital or drs office. yes I still have questions and I'm no Dr or nurse but I'm not stupid! and I have a strong opinion on many things, no one will be able to change my opinion. I'm not the type of sit and tell someone they are wrong about their opinions I will listen and most of the time I agree with them to a point. everyone has the right to their own opinion and I respect that but once you come out me trying to make it seem like I don't know what I'm talking about or call me stupid I will prove you wrong if I'm right. I listen alot I don't speak much but that's how my mama raised me. your respect others even if you don't agree
