Anxiety neurosis. Cure for this problem?

Hi. myself Mr Charan. Suffering with Anxiety neurosis, since past year. i am a orphan by birth. I dnt have love in my life. In this journey,  At a certain age I felt in unconditional love with some 1, & i have trusted her more than me. a year back, She was cheated me ridiculously. Since that time, i was keep on thinking about that cheating, & with out knowing, i was countinuously running with those thoughts & at a certain stage i was unable to controle my mind at all. Now i am facing the problem of frequent urination & rapid thoughts. I am a techie guy, i was drawing best in my industry, i got my own patents in different technologies too. But, Because of this mental condition, i am unable to concentrate on my  ambition. Is there the permanent cure for this problem ? Im not expecting treating, but talking about cure. Plssssss help me.  Kindly reply 😭😭😭😭
