The noise in my left ear. I've done.

When I was in my 9th grade there was an insect or just an ant in my left ear and because of that I feel uncomfortable , that time I am panicking and don't know what to do. I get a cotton buds and I accidentally pushed it so deep and then after that I put some water to my ear and then I'm shocked that there was a lot of dirt coming from my ear. After that incident , I always hear a noise just like a buzz in my ear. There was a second time too that my left ear entered by a small insect or just an ant. I'm not sure because I'm failed to remove it. This happened a month ago that I'm now in my 11th grade , I am panicking that time too , I didn't find a baby oil that they say are good for ears so I put an water again because of panicking and this shocked me too because the water that I've put in my ear didn't go out. I have not consulted the ENT yet and the noise are still going. I'm worrying that this may affect my study. I think my eardrum is damage because of what I've done.
