Stop pleasing someone to stay in your life. If they want to leave, then set them free. It's not bad to remove some shts in your life. Sometimes, there are people  that will became a blessing to you, but in the end they will just become a lesson. Some people are not meant to be part of your life. Don't you ever forget to love yourselves, everybody will leave you, but not yourselves. Maybe there are times that no one can help or even understand you, but always remember aside from God, you have yourselves.
