The worst day ever

I had the worst day ever:

Well last night I went out with my friend Robbie, we had a few pints, not a lot but enough to get me to the falling over stage. Consequently I did not sleep well, feeling sick and needing to pee and being generally a pathetic drunk because I'm not very good at being drunk.
This morning I was working a shift at Oxfam, I was extremely anxious because I usually work shifts with Jacob, so I'm not on my own with strangers, which I hate more than anything. I was feeling ill and hungover and that was my fault but whatever. I was really struggling to do anything because I was so wound up, and the other woman on with me, Sharon, was really bossy and horrid.
Today was also my first shift at my new job at Next. I finished working at Oxfam at 1:30, supposedly. but at 12:30 I had a panic attack because I'd missed my Job Centre appointment, which was at 10:00. I rushed as quickly as I could (on crutches) to the Job Centre, and had to wait AGES to be seen. Whilst I was waiting I phoned my friend Jake to ask him to come into town to see me before my shift at Next, because I was nervous.
So I did the job centre thing, then went to meet Jake at Oxfam, he wasn't there, because he'd gone to find me at the job centre, so I had to go back into town to find him. I then had a massive breakdown and panic attack, I had no money for lunch, and I was freaking out about my first shift so much, I was cobbing in the middle of the street, begging him not to leave me, until eventually he got pissed off with me, and left me in tears at the bus stop.
I got the bus to the retail park, walked into Next, crying my eyes out, the woman who was supposed to be in charge of me calmed me down and then I started working. The other workers were pretty nice, though not the usual sort of people I spend time with, but I was in agony within the first hour. The standing was too much for me, and I was so panicked and nervous and scared by it all and I kept dropping things and generally being useless.
So at 5:00 my break came, I went into the staff room and just burst into tears. First I rang the manager of Oxfam because I was scared and wanted to speak to someone and she was the first person who popped into my head. She told me to ask if I could go home. Then I called Jake and he was bloody useless because he was tired and peed off with me, or whatever, then I called my friend's mum who always gives advice and she told me to ask if I could go home too. So I did. I told my manager, well, sobbed at her a little until she said I could go home. I got back to where I'm staying at the moment, hungry and in agony, and I feel like the biggest failure ever. Who gives up on a new job after three hours?!
