My age 22 I loved a person in my family and we both love each other and have physical cooperation from 3 years. She got married 8 years ago and Living in near house. Now we started misunderstanding and got disturbances. Now she is rejecting for sex and not even being good. And I love her more I thought that was not love. After thinking more the times I confirm myself that was love and I am unable to focus on other persons also. All the times I am going her and she is not being good and I am literally getting mental. I am unable to eat and unable to focus on other things. 24 hrs thinking about her only. At last I asked her to give love. I am literally getting mental and behaving like psycho. Mind even can bear without seeing her. When she look nice at once I am very happy at that time then after if she react and wrong again mind is getting mental. Crying all the times that I love her. And my emotions are changing from time to time. Badly I am not even at me mind is thinking at some where and getting bad thoughts. I think I became mental. I can understand the difference behaving like psycho. 24 hrs thinking about her and watching that he come to online in WhatsApp. We do not message but looking like that for 24 hrs. No sleep also. Daily sleeping approx only for 4 hrs. Now presently I am feeling like half unconscious in brain. Please suggest what to do? I am unable to leave her love and even can not bear without sex.
