Brake lights not working

Hello, this is my first time asking online for help with my car. Sadly I'm a typical female that don't know much about cars. But what I do know is that putting new bulbs on for brake lights and they quit working again like a month later it's not right. My right turning signal hasn't worked for a long long time. My right turn signal was dangling down until I zip tied it back up to something. I'm pretty sure that's why my turn signal doesn't work, but as I was reading messages on here I came across somebody describing that turn signals have something to do with your brake lights. Do you think that is what's wrong with my brake lights? But my brake lights have worked before but my blinker hasn't worked in a long time though.
