Is a carer a real job?

Laura
I have been a full time carer for my SO for almost 4 and a half years now, but something that a family member said recently has really upset me.. 
This family member basically said that because I am a carer that does not work for an agency (I get Carers Allowence instead of an actual wage) that this makes me a 'fake' carer, and that it's not a real job! 
Is being a carer at home for a loved one instead of an agency that employs them classed as a real job? Or do people actually think that it's just the 'lazy' way out? 
I'd love your opinions!
