Hi I know the relationship matters a lot in every body's life. but do this you are not able to concentrate on any activities in life. I do understand the emotional disturbance, but don't you feel there are other things in life which might give you happiness, in learning different things. may be you need to introspect on your skills, interest to to grow and perform better in professional life, strengths and positive side of your life. take care, stay positive, don't lose self / confidence.
