My mind is full of lustful thoughts and i think the devil is trying to put me into a dark place . Im not a bad or sick person but my mind is overwhelm [Spirituality & Religion]

That is the problem. You did [u]not[/u] let her go three years ago, if you are still fighting this battle. This will take a conscious effort on your part and the answer is to pray. Stay in prayer and talk to God about it and ask him to help you move forward and not stay stuck in the past. There's nothing you can do about that and so you must train up your mind to think on other things, positive things. It takes training and all you have to do is practice doing that. When these things come to your mind, get busy, do something else, and pray and God will give you the strength, but you have to make that choice. This happened to me one time and I know how miserable it is. But you can do this. Sometimes our mind plays tricks on us. Sometimes, as I found out, it's not the person that we are grieving over, but what [u]might[/u] have been! We grieve that we lost something we only [u]thought[/u] we had and that can really cause stress. God wants you to have so much better. That old saying is true. Change your mind, and you will change your life. There's no need to stay stuck when you can be active in your own healing. God will help you but you have to do your part as well. You must resist the temptation to think about her at every hand. Staying stuck in the past is not going to help you heal and you must move on because there is someone out there perhaps feeling the same way you are, that needs you and is waiting for you. Concentrate on that and how wonderful that new relationship, that is healthy, will feel. Get excited about that and think of what she looks like and how wonderful and beautiful your relationship is going to be. Because she will treat you like you deserve to be treated. Think on that. Get excited about finding her and when you do, all this other old stuff will not even bother you I guarantee.

If you seek refuge from this crazy world, talk to Jesus.

I've used this over and over, very successfully. We must never underestimate the power of prayer. When we are overwhelmed, that means we've taken on way too much for ourselves. Make a conscious effort to put yourself first and get the rest you need. Instead of focusing on the problem, put your focus on God. Keep your eyes on Jesus and things that have to do with Him. Trust in Him and His promise, that He will always be there for you. I know He's never let me down, in 45 years of knowing Him, and I've been in the worst storms. What He's done for me, He'll do for you. He has no "favorites". Just ask. This is the way you build your faith, by trusting. He is trust-worthy.

When Peter, from the bible, stepped out of the boat, towards Jesus, as long as he kept his eyes on Jesus, he did not sink beneath the angry waves of the storm. But the moment he took his eyes off Jesus, fear set in and he began to sink. Keep your eyes upon Jesus. He stills the "storm" inside us. His Spirit brings peace and comfort. Let Him have your every fear. He will work it out.

"Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee." Isaiah 26:3

It sounds like you haven't been with someone for a long time and it is getting to you. Your body is craving that physical contact and intimacy with a person. But you have been through so much trauma it has scared you into being celibate so to speak. It's not the devil unless you are out to do something illegal or hurt someone.
"[i]Now concerning the matters about which you wrote: “It is good for a man not to have sexual relations with a woman.” 2 But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband. 3 The husband should give to his wife her conjugal rights, and likewise the wife to her husband. 4 For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does. 5 Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.[/i]"

Lord Jesus help this man find someone to love him and he her.Let him move past this bad breakup.You are lonely mate

All this you are feeling is totally normal. And yes the devil will do whatever he can to drag you down. If he can’t he will make you miserable. Seek out other brothers in Christ and join accountability groups. This will help. I promise

Yes I can relate.

Maybe you're just lonely
