This does not necessarily mean you will end up on medication. There are tons of things that you may not know how to leverage that can improve your mental health and overall happiness.
Know that it will take some shopping around. As with any doctor, do your homework, ask friends, and don't stick with one until they "feel right". The modern world is hell on brains that evolved to fit a very different environment than the one in which we live today, and it can take a lot of work to structure your life to deal with that.
Also, remember be both kind to and honest with yourself.
It can be so easy to beat yourself up when you fail or fall down, or to try and shift the blame to other people, but these are both anti-patterns.
Nobody makes every shot they take. Especially when you are learning. Pick yourself up, take a breather, think on what your next step is, and get back in the game.
