My dad's telling pretty much everyone he knows I'm a failure and how he's disappointed in me. I achieved ACC for my AS results and I thought that was pretty good considering I was predicted CDD. Despite all that, my dad sees the 2 C's and pretty much makes me feel like the biggest failure to the point I actually cried. He's comparing me to one of his friends' daughter saying 'She used to always be worse than you now you're worse than her' and other BS that's really annoying me.
I seriously don't know what to do anymore. Even at GCSE's with 6 A's he was disappointed that I didn't get a single A*...
I hate myself and even considered just ending all the disappointment with self-harm but that would be so stupid of me. I just need some advice on what I can do regarding my dad and how to not let it get to me.
