Hi. Getting over relationships can often be very difficult. But then moving on in life is equally important more so since you are in a new relationship. Any current relationship must be given more importance than past ones.Since you are having suicidal wishes as well, it will be advisable to seek professional help at the earliest. You should see a psychiatrist and get yourself evaluated. Treatment either in form of medications or counseling or a combination of both can help you feel better and move on.
