I Have My Ears Pierced

I just pierced my own ear yesterday and totally regret it😭
I had been debating to do it for like 6 months then just decided to do it. Bought all the supplies. Watched tutorials and read articles.
It seemed okay.
But now I'm reading all these articles about getting ear infections and all the things I bought to heal it (hydrogen peroxide, alcohol swabs) are apparently dangerous. Can't take it out cause that will cause more trouble, don't have money for sea salt solution at the pharmacy so I'm just stuck with the anxiety of something going wrong🙁
