Uni admissions test and 5th monthiversary clean on the same day

So basically on the 13th I have an admissions test to my dream uni where I want to study photography. Also on the 13th I will be 5 months clean.

Had a pre talk with someone at the uni to kind of tell me if my pics are going in the right direction of what they are asking and he said yes to all of my pics. But I‘m still scared they won‘t accept me and that I‘ll relapse on the 5th monthiversary. Was thinking of treating myself to something because of the 5 month mark but now I‘m scared that I wont get in and that I‘ll relapse… :/

Anyone got any tips or sum? Feel helpless and scared of myself.
