Depression maybe?

It's been over 6 months since I graduated as an engineer, but I do not look for a job cause I didnt wish to work as an engineer anymore. Realised it was not my cup of tea. I have found a new field and n m looking foward to it soon. but it will not start before September 2014. Hence, Ive been home. I studies for some entrance exams back home, but didnt do well, and I my family which includes my mother and my grandparents (my mother's side) who are very caring towards me are nothing but dissapointed. It's not their fault also. I keep trying and failing. But I just wish they could understand that I am just 22 there is still time, a lot of time for me to figure out what I want. I have been so depressed lately, it has made my self esteem so low that I fear attempting anything else, even a new hobby that I'll fail at it again. I have stopped talking to my friends , as I dont want them to ask me what I am upto, I do not want people to think of me as a waste. All I know is that I am capable of so much. I just need time and opportunities. I have chosen a new path, a fresh start, planing to go abroad but not before September 2014. And I know this time I'll rock it. But for now I want people my family to leave me alone and be supportive. And that is for my grandparents. For years they keep comparing me to their relatives' kids who are doing exceptionally well. It's heartbreaking. The only good thing going for me at the moment is my optimism, that maybe after a year or two or three, m going to be so successful. I JUST NEED SOME TIME.

You need to not listen to what others think. If your family put you down and make you feel bad about yourself then they arent very supportive but this is quite common with families. Perhaps you should think about getting a job to tide you over till you start in September. And maybe plan on leaving home and making your own life. You are old enough now to do this. Families want the best for their children but they unintentionally inflict damage. Its not healthy. If you stay there you need to tell them to back off and let you find your won way. If they cant do this then the only alternative is to leave.
