I want a job...

I want a job but I'm nervous. I want a job to help out financially. I also don't like sitting at home all day. I just had a bad job experience and it has made me scared to get a job.  
My first job ever (besides babysitting) was at shoe carnival. It was easy to work there but the manager treated me bad. They weren't abusive or anything. 
Some examples:
They trained me on the cashier and merchandise for 30 minutes (literally) and got angry if I didn't know something. 
They yelled at me because my car broke down and I was a little late (I even called as soon as it happened.)
I got yelled at for talking while we were putting the alarm things on the shoes. 
I called in sick (my throat hurt, my head hurt, I was coughing, my nose was leaking). Well they told me to come in anyway. I did and they yelled at me for coming in sick. 
They yelled at me in front of all the customers because I was slow on the cash register. I do admit that I was slow at it because I wanted to do it right. 
And more. They yelled at me a lot and it has really made me nervous to get another job. I quit after 10 months. I have not had a real job since then. I did a whole lot of babysitting but that's it. 
I'm sorry that this is so long. And I'm sorry if I seem whiny. When I start to fill out applications, I get halfway through and throw it away because I think 'I have nothing to offer this company and I have no job experience.'  Why would they hire me over other people?
I know I'll never get a job with such a negative attitude so what I'm asking is how can I man up and get over this irrational fear/nervousness?
