Liquid damage to macbook

so I basically spilled milk all over the keyboard and Touch Bar part of my computer, everything was working fine after I dried it up and cleaned it. I used the computer for a couple hours after thinking it was no big deal then all of a sudden my computer crashes and I’m not able to turn on the computer and the Touch Bar is also not working. The light from the caps lock button is working and whenever I click on the Touch Bar twice it says “username” or “voice over off” . I am not sure what I should do about this since there are no available appointments with Apple on the next 7 or 8 days, any suggestions? Thanks in advance
