What can I claim?

Hi im a recent amputee below right leg with an epileptic partner all i claim is pip and i get carers for looking after Angie. My partner our rent is paid and we get help with council tax. My partner claims dla in her own right industrial injuries and esa. People say i should also claim esa or job seekers allowance. But never claiming anything in my life no idea where to start or if i would get anything. Plus dont want it affecting my partners allowances as we are only just managing now help
