Employment and benefits

I wonder if someone has been in the same situation as me and can give me some advice, iv had pd now for about 11 years I work full time but im getting very tired and starting to struggle a little by the end of the week. I wonder if anyone knows if I could get any benefits to make up the money I would lose if I dropped a few hours and went to part time.Im sorry if this is in the wrong place
I suggest ringing the helpline, they have a person who specialises in benefits, also get in touch with your local Parkinson support worker. Both have helped me.
