Personal life : Is't my problem or your problem?

I  think I have to leave architecture for good. I just cannot cope with it anymore... I cannot take the challenge anymore.

It's frustrating to see my design going nowhere but fail. I'm tired of motivating myself every time after gone for crit sessions with supervisor. I'm all so tired talking but get no respond but just yawning and boring look... I frustrated and got all the harsh comments. Maybe I'll just get a B- this time.

I admit it that I'm a looser and lazy. I'm all burnt out.
