Dealing with Workplace Mistakes and Overwhelm

I think the thing that helps me the most in situations like that is reframing the way you think about it. You were doing your job properly, this coworker was not. She didn't follow the initial instructions and failed to send you a quote. That isn't your fault and you did the best you could with what you had. It is her fault for not getting a quote in in a timely manner and, quite honestly, too bad if she doesn't like what you put bc she didn't reply to you lol. Maybe there was some kind of technology error or failure that prevented her submission from reaching you. If so, that is still not your fault and she should not have accused you of anything but calmly asked whether or not you had recieved it What I'm saying is, the incompetance of others isn't your fault. I know your anxiety might try to tell you otherwise but other peoples actions are out of your control. You can't control if your coworker is irresponsible or how they react to your handling of their mistake, but you /can/ control how you think about it. It's okay to feel bad, she's upset, but from what you've shared she is the one who messed up here, not you In the future I would say don't be afraid to send follow up emails if you didn't previously! If someone, like your coworker here, doesn't get back to you within a few work days, send a very nicely worded "Hey! I wanted to check in with you about __. I need to know __ before next Wednesday" or whatever. Sometimes my anxiety tells me that is annoying or bothersome but it's not! You're doing your job and need that info to complete your task so follow ups are completely reasonable Hope some of this helped and that your workplace experience improves!
