What kind of job should i apply for?

i have qualifications in photography but i dont have the confidence anymore to start my own buisness..i have worked in retail, but im not good with money and dealing with customers. i keep getting fired from jobs for making mistakes, and have just got fired from a factory job because i got bad rsi in my shoulders from the repetitive work which is still painfull after a week..
i have arthritis in my feet which causes me pain too..any ideas would be great.

You should see a careers adviser.

try an office job, or telemarketing. depending on if your male or female you could get a job as a receptionist where this is minimal responsibility apart from not upsetting clients and being polite, and if you're a telemarketer, you'll probably get hung up on anyway.
try an office job, or a job with low physical requirements.

You're probably good artistically if you've done photography. Have you thought about doing some further study? You could always go and study graphic design or something like that and work in advertising.

If you have a bachelors degree or if your older and have allot of life experience get an emergency teaching certificate and teach.

I agree with Jerry. A job on the net would be good for you. And it doesn't mean you won't be able to be successful. Good luck :)
