Oh my gosh have I ever dealt with it. I was raised in a Christian cult, spent years researching Biblical manuscripts and experiencing world religions. Praise God I had a personal experience with Jesus when I was at my lowest point. He picked me up and held me close and He has never been too far away to hear me when I cry. It comforts me to no end to know that He understands me, and forgives me when I am angry. He suffered unjustly too.
He used me during the good years as a phone counselor for the Billy Graham Assoc, I served on several different ministries like homeless ministries. Married a pastor 5 years ago who is now retired from church leadership. Worked in an Internet ministry providing help to cult survivors. I spoke at a convention of cult survivors, if you are interested I'll send you a link to my sermon in a private message.
Though I too have lived the Christian life experience, there are two things that really bother me;
1# People/Christians who tell me "remember there are others who have it worse than you do". OK GREAT! So life sucks and then you die for other people too! Thank you very much for that encouragement I feel so much freaking better now.
#2 People who preach to me or send me as you said "inspirational" sayings with the intention of HELPING me with my attitude or anger. Jobs best friend did not try to fix him like the others, the best one just sat with him, was there for him. We have to cut them some slack though because they could never understand what this is like.
My relationship with God changed when I got mad at Him. I did. He can take my anger, He allows my suffering, but He is not leaving me to go through it alone. I've stated this before: I have lost faith in the church, in my family and friends, the medical field, even my husband, but I never lost faith in Jesus. See, He already know how we feel, it just makes it all better when we tell it to Him from our own heart.
One time I was so angry at Him I would hear the Spirit call and I would say, "talk to the hand Lord I've had enough". We will always come back to the cross because He will never let us go too far. He forgave me and again brought me back. This suffering brings a deeper dimension to me on what it means to pick up my cross and follow Him. Some days it too dam HEAVY! Then other days I realize He is carrying it for me.
