Don't suspect him, maybe he is cheating but don't assume he is until you have a reason to suspect. If it gets obvious that he is then talk to him. If he's not cheating great. If he is... then break up and move on. Suicide is never the answer. Remember to Smile!!!! :) You are loved by many and there are always other fish in the sea!!!! Much Love!
Hey Priya ! After reading you post I can understand you situation very well. But I strongly suggest you not to take any kind of medicine without the advice of any psychiatrist or doctor. It may be very harmful......so don't think about that. If you really think you have depression....any need medicine than you must go to any known psychiatrist.
Second. There is not need to do suicide dear.....
As you have said in your post that you are not from city and your boyfriend is from city....so obviously he have many friends who are girls....and you do not like this. Right. ?? I think this kind of narrow mindedness can harm your relationship. [you accepted yourself that you are narrow minded. ]
May be you are jealous ...because you love him but this kind of jealousy would be harmful for yourself and your relationship. You should understand that in cities boys and girls are more open and talk freely so you should not suspect your boyfriend. You must have trust on you love..........
All your depression problem and restlessness is because of your attitude about the situation.....Change your thinking dear.....and you will see that you feel more light,relax and happy. I hope you can do this,ok.
best of luck.
