I did last year too. I was barely managing during the first two years of my undergrad. Then when the important events came along, such as presentations and interviews, I could barely manage. I could not even answer basic stuff like 'Tell me something about yourself '. I completely withdrew myself from life, did not even apply for any positions, stayed jobless for six months, got into the worst possible company that too with a contact. Then spent an entire fortune on a master's degree. Halfway through I realised I had no hope and there was no other option. It has been more than a year since then, and still find very less motivation to go on.
