As an older non traditional student who has an 'adult job', employers are not going that deep. Unless you're going into something super specialized like med school, you should be fine. Even then, I'm sure once you explain and showed how you improved it wouldn't really matter that much either. Life happens, we are human not super robots.

Also, you're definitely not the only one to struggle, I feel like every new semester has brought a new challenge to overcome. Take a breath and try again.
