So... What do I do?

I'd tend to go along with Serfdom's advice. I'm a bit out of touch and I assume the catering A-level is one of the new vocational A-levels? I was a boring dad and always advised my kids to take subjects that interested them when it came to their A-levels. That time is precious, but so challenging, and you might as well take the opportunity of digging deeper into areas of learning that fascinate you ... I must admit it led to some strange choices, but it's their lives and they are all doing okay and have mostly ended up doing what they were keen on.

I'm more concerned about your depression. I hope you are getting help with it? As a sometime fellow voyager along that path it's all too easy to be overwhelmed. Unfortunately it doesn't sound like your mum is being as supportive as she thinks she is. I don't suppose she is also depressed? It can affect more than one member of a family.

You need to take care of you. The education is rather pointless until it all makes more sense.

Good luck
