Looking for healthy ways to cope while waiting for my college documents to process

[amSleepy]

For context, I'm in the process of re-admitting myself to my old university; they stated that the requirements for re-enrollment are non-negotiable, and I'm missing approximately two documents. My current university is in the process of finding those remaining documents and said that they'll contact me once they find them. In the meantime, I have no other option but to wait it out, and it's stressing me out. I can't help but catastrophize and think that maybe I won't be able to re-enroll again. I'm always struggling to find healthy ways to cope with the stress, especially since these last few months haven't been so good to me. I would really appreciate any tips/advice/or healthy coping techniques, or any healthy way to get my mind off the fact that all I can do is wait and hope for the best. TYIA!!!
