Once you discover your creative passion, you must perfect those skills. Like anything in life, If you want to write, then write, a lot, if you want to take pictures well then, go out and take pictures, you have to perfect your creativity, not because it's a job but because you enjoy it, then you need to try something that allows you to focus, be it painting, drawing, photography or writing, etc.
Another person's day with something you created? so be optimistic and constructive instead of becoming passive and pessimistic, it is a very destructive habit in the long run for your motivation, happiness and self-esteem.
Control your feelings, your emotions and your thoughts, the realization that this helps you deepen to life, take action to resolve the situation or to move forward, concentrate only on the same with that, keep moving forward towards something better, even if you stumble again.
Try breathing techniques, meditation, yoga, exercise to help you with anxiety, all these things are fantastic and they work to a certain extent, they help you to feel calmer and healthier, if none of them free your mind from anxious thoughts or the feeling of falling with nothing real to cling to.
