you failed? go on cry it all out, be angry, be disappointed, complain all that you want. but i want you to think about a couple of things: will it affect your life in any way? are you going to remember it in 10 years, 5 years or even in a year? i bet you won’t so don’t think you are a failure, don’t hate on yourself. you will make mistakes, you will fail hard but you will also learn from them, you will grow and you will get better.
Different feelings will come and go. When they do, allow them to stay for as long as they’re meant to. Fully experience them, for pushing them away without acknowledgment will only make them bubble up to the surface at a later time. Don’t force happiness. Don’t force positivity. Just feel what you do, and develop from the experience.
