How to not drown in sadness

Dear listen , if someone says "you are supposed to have a great life " like look at your life and it's going amazing and then you see your life as happy , everything you want , you're in love with your life but when you grow up , you see things changed , but you remembered "THAT YOU WERE SUPPOSED TO HAVE A GOOD LIFE" so you accept that it's your good life, honey life changes when you change your mindset , so don't get negative, it may seem hard right now , but your life will blossom too❤️❤️
