Hello, I'm Not Sick Or Anything I Just Want To

Hello, I'm not sick or anything I just want to ask something. It started when I was like 7 or 8yo I was having a normal day that time but there was like a sudden change to me, I don't know how to explain it but the normal noise or sounds that I hear everyday in our house(for example, my parents speaking to each other or voices coming from the TV) starting to get louder and louder. I got scared and panicked so I started crying and calling my parents telling them "It's loud" so when they tried to calm me down I got more annoyed and irritated by their voice like it hurts my ears so much. Every noise that I hear was really annoying, bothering and irritating to me. I can hear my heart beating so loud in my ears, my heart was beating fast and I was sweating so much. And this happened to me more than twice, the last case was like in 2017 or 2018, it was at night where I started hearing my heartbeat, it was so loud and was beating so fast, and I started sweating and instead of hearing loud noise, my vision became really weird... I don't really know how to explain it. The objects was like getting big and small and whenever I look at my mom her figure becomes really big and really small(in my vision) but this time I found myself a way to control it, I keep telling myself to be calm repeatedly and keep telling myself that this will stop soon and it works sometimes for some reason though it takes time for it to stop. Why do I encounter or feel these things? What are these? Is it an illness or something? And I also found out that this thing can be triggered by sounds. When I was playing a mobile game, the music of the game was on and the volume was very high too, and again I started hearing my heartbeat, it was so loud and it was beating so fast, I started to sweat and the music was getting more louder in my ears but not to the point that I'd start crying. I don't know how to tell google about this so I went on this website. I'm just really confuse on why I feel these things.
