What can I do to help school attendance?

I've realized I have extremely poor attendance and now my mum is being tracked down by social services. I don't want to ruin her life because of my actions, and I'm sure if you were here in my situation, you wouldn't want that too. I want to do something in school that will sort of stop the headmaster. I have 60-70% school attendance and I'm very ashamed of it. My mum is also going in on Wednesday for a convo about it, and I'm worried. What can I do?/
