Heartbreak is painful, and it is worse when we are hopeful of something positive and then nothing happens. I can understand that you must be feeling very upset at the moment. Take some time to grieve and heal. Spend time with friends and family, distract yourself. If after 2 weeks also you don't feel better consult a psychiatrist for a detailed evaluation,you might require treatment for depression. Depression is a illness like any other and can be successfully treated.
