Truth is based on one person: Jesus.
Not what someone tells us of Him, but what His Word reveals about Him.
It could not be any simpler.
Yet for the longest time, I was convinced that if I had negative thoughts or feelings, then I was dead-set responsible to do something about what I was feeling, to get rid of those bad feelings, so that they would not trouble me any further.
That is not the life that we are called to accept.
We are called to walk in the truth, and accept nothing which rises up against that truth of who He is and what He has done:
"(For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) 5Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ; 6And having in a readiness to revenge all disobedience, when your obedience is fulfilled." (2 Corinthians 10: 4-6)
Notice that Paul writes about the obedience of Christ, not our obedience, but His.
And what is His obedience?
8Though he were a Son, yet learned he obedience by the things which he suffered; 9And being made perfect, he became the author of eternal salvation unto all them that obey him; 10Called of God an high priest after the order of Melchisedec." (Hebrews 5: 8-10)
He suffered for our sins, our sickness, our sorrows, for everything. He was perfected, in that He completed the work and rose from the dead. Today, He is our High Priest, and He is justifying us at the right hand of God the Father now and forger (Romans 8: 31-32)
We need to see Him, and He transforms us to be like Him:
"But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord." (2 Corinthians 3: 18)
"1Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not. 2Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. 3And every man that hath this hope in him purifieth himself, even as he is pure." (1 John 3: 1-3)
Not looking at ourselves, but Himself. Not fighting with the lies, but resting in the truth: that is what this life is all about!
