I regret everything

I've been wanting to do like an ombré for like a year and today I did it but I was dumb and lightened my ENTIRE HEAD. My roots are super light and patchy and bronze and I did a color correct hair mask and it didn't do anything and I have school tomorrow and ik people will comment. I didn't realize my hair was such a security blanket for me but I feel so shitty rn. Im scared to try to box dye my roots darker and I don't have enough money for a hair salon. I need something to do to hide it for the next week at least
