Thanks for the feedback you all ...
I ... Well, I realize that I cannot abandon Sunday services because of the people who are coming back to church (besides everyone else ...). Not many people asked, and not many people ask what is going on with me, but one particular young woman who's being reconciliated with church came to ask what had happened with me, and it cut my heart! ... I need to be there.
But not only this, the preaching tonight spoke about worldly attitudes (Corinth, I, 3, 3) and childish attitudes ("Hebrews", 5, 12), and, together with many things spoken, I came to realize both a worldly way of thinking (related to institutional distresses concerning which I need to be patient), and a childish way of thinking ... I should get to grow up ... I'm 33, and I'm 11 years with the Lord.
I've been sad, and frustrated, but I can't make other people stumble because of my feelings, as Elihu says to Job and his friends: "Look at the heavens and see; and behold the clouds, which are higher than you. If you have sinned, what do you accomplish against him? And if your transgressions are multiplied, what do you do to him? (...) Your wickedness concerns a man like yourself."
I'm going through some tough time, because the bible-talk group I'm in is in a particular crisis, falling appart ... I'm feeling bad with it, but I have to face it, and go ahead without damaging other people's faith.
