Possible getting it re-pierced??

So I was 16-17 when I got my cartilage pierced, now I was really happy because my parents surprised me with it and didn't know anything. 😅

The mistakes that happened:

- I went to pagoda in the mall.

- She used a gun not a needle.

- She was in a rush.

- The piercing it self was too tight.

-Found out she used the wrong earring.

-Cleaned it with achool and was told to twist it to keep it clean.

The result of this was me getting a bump on my ear, I showed my mom and she said to take it out. then few days later pus came out and she popped it.

I'm 19 now and my ear looks like this.

Can anyone help me please, I really want to get my cartilage pierced again
