Any cosmologists on here?!?! BLEACHED HAIR GONE WHITE AND ORANGE?!?

Long story short, I did my own blonde back in October. I an naturally a dark brown. I redid my roots at the end of December and thought all was well because they came out somewhat good. I was stupid I had a stressful day at nursing clinicals and decided to do my roots at 10pm. I am so screwed, and my birthday is in 5 days. I have no idea what to do. I literally going to wear my hair in a bun with a thick headband to cover this up. I understand I screwed up and I am stupid. You don't have to tell me twice. Just wondering which box dye color would u do this or if my best bet would be to pop into Ulta tomorrow after clinicals and let them know what happened and see what they can do.. At this point I don't care what It is. I still want to be blonde or like I was before.. I just should not have done this. What do I do?!
