Waswasas of talaaq

I am a mental patient and I have a lot waswasas in each activity. Every minute and second I have a lot of thoughts and what I think is repeated by me orally. I am very worried about this problem and this problem has been for 3 years. When I study I repeat one word many times and I cannot control it. Then to avoid these thinking I said to myself that if I think, my wife will be divorced on me. But I cannot stop thinking and in my mind the same thinking takes place. I say to myself to repeat the word "I have not given divorce to my wife". Now I have this waswasas in my mind that I divorced my wife. I am very sad about this problem. Please Mufti sahib give me a solution for this.
