Why am I here?

I feel like I'm slowly losing it. I've been trying to keep it all together and pretend like I'm ok but I'm not... I haven't been able to get a job. I get anxiety just filling out applications. Not to mention the pressure my family is putting on me. I don't really have any friends. My so called best friend hasn't spoken to me in months despite my attempts to talk to her. I got into a fight with someone while I was intoxicated and now my whole family sees me as a drunk. So I guess no more drowning my problems in alcohol.... I feel like I'm suffocating. There is more to my story but in short everything just has me questioning my existence. I just feel like I can't do anything right and no one wants to be around me anyways. So why am I here?
