I know this deck is at least 1 week old already, but I just wanted to say that you shouldn't feel guilty or bad. You still have a lot of time and you shouldn't focus only on what happened in the past. Think of your experiences as lessons that you can look back at, not something that holds you back and makes you feel worse. Just try believing in yourself and try doing more things next year without overworking yourself. Still, remember that we are just humans and we will do various mistakes throughout our lives. You also shouldn't expect too much things from yourself, try taking everything at your own pace

i feel you, happens to me too :(
