is this routine too harsh for a very irritated skin ? Did I permanently destroyed my skin barrier?

Two months ago, I messed up my skin.

I used way too much of the vitamin c suspension 30 from TO with some kind of weird greasy soap which I thought was a kojic acid soap because of its color. When I started breaking out from irritating my skin and clogging ever single pore I had with this weird ass soap, I used undiluted apple cider vinegar which made it even worst obviously. I thought that my skin just needed exfoliation and I didn't wanted to wait and order a new lactic acid peeling from TO. My skin obviously got worst and I kept the idea that my skin just needed exfoliation. Id still use the vitamin c and the alpha arbutin serum from TO to prevent PIH not knowing it would cause further irritation. In addition, it was also a very stressful time for me as I had very important exams to work on while also being illed. I gotta say that when I was 13, I did way worst things like putting toothpaste, NAIL POLISH REMOVER ON MY SKIN. Yes I know. Though my skin never reacted like that in my whole life.

Im 17 now and I feel so bad because of all the weird pustules and cysts and inflammed acne in general going on on my cheeks. I feel like Im a monster and I cant go out with make up, even around my family I feel so ashamed even around them and I feel like they're disgusted by me. And now I'm so scared to go back to school looking like this, even though my skin has slightly improved.

Is this routine good enough for this type of inflammatory acne ? Is it too much ? Is it hydrating enough ? Should I add an exfoliant ? Feel free to leave recommandation of products under 10 € available in France over the counter. I cannot afford to see a dermatologist sadly as I'm still a minor.

(sorry if they are any grammar mistakes or if I didnt spell some words right, Im french)
