The weakness of a person is measure by the lack of acknowledgment of it. The strength of a person is measured by the ability to recognize the strong and weak points and do something about them on a daily basis. I believe you are the later. You know and understand who you are and are working every day on becoming the person that ultimately God wants you to be, therefore, you are already a victor.
As for your question or statement about, “nobody loves or cares about me?” forget this statement. It has no value coming from you. The most important question or statement is, “Do I love this person, when I dealt with this person today, even if I had to reprimand this person, did I do it with a parental heart, did I do it with God’s heart, or did I do it to release my own frustration towards this person.”
That is the question we should all ask ourselves on a daily basis. If we do that, we will never have to worry about do people love us or not. I am grateful of your sharing on Facebook. That is the level of discussion and sharing I like to have with others. I appreciate your effort in wanting to make us think and read and pushing us forwards. You have the mark of a great leader.
Don’t give up, you have a beautiful family and I have no doubt that they love you.
