I wish thoughts didn't have such a huge impact on us

I have started thinking about this more and more and realizing how thoughts can just eat you up from the inside without you realizing a thing. Thoughts are created by what we see, hear, feel etc. Thats why I personally think we should be extremely careful what we expose ourselves to. We all know our own bodies and what affects us, but a lot of things in this world affect us more than we tend to realize. When I was younger I listened to a lot of music and I let it get to me. I only realized years later that I thought about exactly what they said in the songs and they kinda hypnotized me to this state of mind (depending on what the song was about). It had such a huge impact on me and I found myself depressed in my room so often and I didn't know why. The songs made me wanna be sad and made me want to feel more and made me wanna be something else. 

If you don't get what I mean, a typical example that I'm sure you have had would be listening to a happy cheery song. You know that moment when you become really happy just listening to the song and you wanna dance and jump around, well the same effects come from all different genre/types of songs. If a person listens to a lot of depressing songs, they are more likely to end up depressed in my opinion. This is because the thoughts will take over you. I randomly came across a picture of a bible with a scripture (photo below) that pictures exactly what I think perfectly. So I decided to post it. 

Another thing is that when you have a little worry and you think about it a lot, it becomes a big worry. Thoughts take control of a person so easily that I think people should be more careful. Of course we are all different but I think to some extent this goes out to everyone. I decided to make a change and I deleted all my music. I only listen to songs on youtube if i remember a song randomly but I don't spend my days listening all the time and when I get sad I don't dwell on sad music anymore. I have noticed a huge change in the past about half a year. When I hear those songs what had a huge impact on me earlier, I feel this thing inside me that brings back a little bit of that down feeling that it would eventually give me and thats why I know better now.
