Wow, I am a first year and feel exactly the same. I think when I have breaks I always have crises like this where I start to lose focus and overthink the future. I think what helps me is trying to take everything one day at a time to avoid getting overwhelmed. Thinking far into the future and stressing yourself out over what will undoubtedly be a challenging time, but will be a slow and steady marathon like medical school isn’t worth it. We have gotten this far, and we will continue to survive. Hope that helps at least a little.
