am i entitled to any help

hi,

my girlfriend started an apprenticship today, so i have been to jobcentre to sign her off. They told me i have to sign off and i am not entitled to any benefits,

She is 23 i am 42 and i have a disability (brain aneurysm)
i was claiming jsa and disability premium allowance plus my low rate DLA. now that has all stopped.

she will be earning a measly £3 an hr ,7 hrs a day ,4 days a week + 1 day at college.
we live in a 2 bed flat so already paying an extra £10.25 a week + £4 a week council tax on top of our council tax/housing benefits.

Are there any benefits i can claim? job centre told me no because she will be working more than 24 hrs a week so is classsed as full time employment even tho its an apprenticeship/training.

i dont like the idea of still having to sign on to recive nothing.
i am searching for work too but my disibility doesnt help me, my advisor told me to look for part time work up to 16 hrs a week, and something about tax credits .

i really would like some help and advice no idea what to do.

thnx in advance
