Thank you everyone for your replies. Sometimes I feel like I'm so alone in it, and everyone wants to see me fall! Well they got very close, it's all your replies that made me realize I'm not an absolute failure. I know I sleep late, but it's because there's nothing to do. Mum snidely remarks "House work?". Well mum, that takes a maximum of what, 2 hours? Then I'm bored again and feel empty and have nothing to do. I currently have nothing to wake up for, that's why I want to start a distance learning course. So, dear step-dad, I DO NOT need to horribly remarking on me being lazy and therefore not being able to do a course.

Anyway

On a slightly more positive note, the same day at night me and mum had a very emotional conversation. There was a fair bit of shouting. She admitted that my step dad "doesn't understand you at all" (you meaning me). In the end we BOTH ended up crying and I think she recognized I neeeded support and understanding, as she begged me to "Stop this! Get out of that horrible world!". I think she realized that when I get stressed I do tend to push them away, especially when it's my own "family"'s doing.

I refused money from her, called her by her first name instead of 'mum', but in the end she forced me into hugging her and we ended up crying and hugging for about 10 minutes.

SO at least, in part, my mum understands.
As for my sister, she said "None of us listen to what your brother says, I know he's given you a tough time over the years, but just do what I do, ignore everything that comes out of his mouth".

Thank you everyone
