I am 22 years old female . I completed my Btech in 2016. Now I am hunting for a govt exam and terribly failing in each exam I give. I know my weaknesses but I am unable to concentrate. I sometimes feel I can do miracles but then when I sit to study I am lost. I feel like every decision is wrong. I had a relationship of 2 years during college. It ended . He moved on but I am unable to. He is dating someone but I am unable to stop myself from stalking him. The old memories of him keep playing in my head continuously. At times, I feel so tired. I want to stop them. Tiniest thing reminds me of him . Though i dont cry but i feel pathetic somedays. I am having major exam in 15 days and it is like do or die. But I am unable to study. I feel like I should die and these thoughts are now becoming recurrent. I have deactivated all my social media accounts and shut down all the contacts to increase my study hours. But I am unable to do. I feel so helpless. I feel like I have OCD of my ex or maybe I am depressed. And also I am not.comfortable with my body. I go gym but nothing works out. I feel like I should end this misery.
