Performed Dermabrasion on myself. Is this normal? Please help! (Photo)

I have a couple of acne scars on my right cheek that really bother me and have been around for 4 years. I tried everything! Microneedling, co2 , erbium laser, subcision, peels (multiple sessions of each) and nothing worked. I got tired of spending money on treatments and not seeing results so I decided to perform Dermabrasion on myself after reading a research article. I autoclaved 120 sandpaper and scraped my skin, then I applied antibiotic ointment. This is how my skin looks the day after.
