Ruining Everything

Ok. So I don't know what my problem is (likely my shitty job if I had to guess) but now it is affecting my life at home. I have become depressed and am taking out my frustration on my boyfriend (poor guy). I know it's not fair but the stress of work has made things rotten. I heard once that when your career is going great, your relationship suffers, and vice versa. So what the hell is going on here?? In addidtion, the so called "urgent" work that my boss gave me is such a damn joke. It's what I like to call busy work and it is lowering my IQ minute by minute. I have a good lead on another job...it's in marketing and it's work from home (which I am not sure is a good or bad thing). Regardless...I am on the verge of quitting. I hate it here. Everyone is so fake and superficial. I am going insane and drowning in the silence.
