I am not gonna say it's okay to feel what you are feeling or a good day will come too. I know how it feels when you feel stuck like that...
When you feel left out even in your own group, when your good friend left you for someone. when you feel no one love you or need you. When you can't live your life as you want. When you feel stuck at everything. When you feel sad and you wait for good moments. You are waiting for right time.
Don't wait, stand up and face this world with smile. If you wait, right time will not come... just make this time your right time... you know you are the only one you need. Love yourself the way you want to feel love.
Sometimes some situations will try us, beat us and break us. But it is out choice to stand back up. Not every day is a rainy day
