Some times we feel like we are not good enough or sinless enough to speak with our Heavenly Father. There have been times in my life when I have felt that too. Sometimes we are left with no choice but to talk to our Heavenly Father, because of circumstances been what they are. He is always there and will always listen it doesn’t matter if you are angry, frustrated, sad or hurting he is there he cares. I know this lady who lost a child, now I would never wish that on anyone to have to experience and I can’t imagine the anguish that it has caused her, however, she chose to trust in Heavenly Father. This has increased her faith and sensitivity to others and it has also sustained her when I am sure she would have rather laid down and died herself. In opposition to that I know somebody who chose to become atheist / agnostic over a similar situation. The difference is that her life is a serious struggle every single day, where I am sure she feels like life is just one never ending nightmare. I have felt the same way at times. I have felt there were days that I just wanted to end it all even though I was reading my scriptures and giving service. I obviously chose not to, however, those days of feeling that nobody understands you are the very days that you need to turn it all over to Heavenly Father and have faith in his plan instead of resisting it with everything you have. The nightmare ends when you let Heavenly Father be in control and trust him!
