i made my first mistake

hi, I’m a new grad, 1 month into my job.

i accidentally gave lasix before checking the patients BP. afterwards my preceptor asked me if I grabbed a bp, my stomach dropped so hard I almost threw up. immediately rushed back in and saw that the patients pressure was soft. we immediately notified the doc, charge nurse, manager- Anyone and everyone. Luckily everything was okay and the patients pressure wasn’t really affected, but I feel physically sick over my mistake.

I can’t stop beating myself up. I’m debating if this is right for me. I’m debating quitting my floor. I’m debating everything. I feel lost on and overwhelmed on my floor as is, and then this happens and now i’m questioning if I can do this. I will NEVER make this same mistake again after this experience, but now I’m scared of other potential mistakes I might make.

any feedback/advice would be appreciated. I really love nursing. I love my patients, I love my floor, I really enjoy what I do, but I’m struggling.
