Our hearts go out to you. Lies and false accusations are very painful and cause much suffering. Is it at all possible for you to change situations where you might start fresh without this burden? It might be worth the trouble of doing so… Pray about it and ask God for direction and wisdom. James 1:5 (NKJV), “If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him.”

Otherwise, how should we receive the buffetings, the trials, the "contradictions of sinners"?

Let us remember that Jesus also endured many false accusations. Consider His example during his trials before his crucifixion. He was patient and long-suffering when falsely accused, beaten, and spit upon. Do we endure similarly, realizing that nothing could happen to us except by our Father's knowledge – nothing that he is not both able and willing to overrule for our good? 

We may not say that if we deserved the evil treatment we could take it patiently. No, we remember the truth of what one of the thieves on a cross confessed, “This man (Jesus) hath done nothing amiss.” 

We cannot say that we have been perfect in all of our dealings with those who may despitefully use us and persecute us. Our intentions may have been the best and we may have in some degree rendered good for the evil we receive. But remember the Apostle's words on this line, "For what glory is it, if, when ye be buffeted for your faults, ye shall take it patiently? But if when ye do well, and suffer for it, ye take it patiently, this is acceptable with God. For even hereunto were ye called: because Christ also suffered for us, leaving us an example that ye might follow in his steps; who did no sin, neither was guile found in his mouth; who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him who judges righteously." – 1 Pet. 2:20,23.

Let us try to be as nearly as possible faultless and undeserving of reproaches and buffetings, but when these experiences come to us let us remember to take them patiently, uncomplainingly. If we do so, we will more and more develop and exhibit the character-likeness of our Lord. Then we will have the Lord's guarantee that every such experience shall prove a blessing in the end. Those who, on the contrary, try to "battle for their rights," show that they either do not understand the nature of the covenant they have made to take up the cross, or else that they are unwilling to comply with the terms of that covenant.
