Is NOBODY wrong in the post ? POST : To start - I am 19F who definitely doesn't help around the house as much as I should. I know I'm lazy sometimes but I do occasionally get massive surges of energy and clean lots. I find it hard to do jobs or work due to depression (motivation and ability to concentrate is unfortunately shot atm). This has ruined a lot for me as I went from being a top student to bottom and I have struggled since with not being one of 'the best' like my mum in particular has always pushed me to be. She is pretty onboard with my bad mental health though.

Today we had an amazing Sunday roast and I helped clean and set the table. I also cleared all the dishes and did a couple loads of clothes washing. My parents asked me this evening to do the dishwasher, which I thought was slightly unfair because my brother (17) hasn't done any household chores today.  
Anyway I unloaded the dishwasher but decided I wanted to ask my brother to load it back up. This is because I am vegetarian and honestly the thought of touching plates and trays which pork has been cooked in, and are covered in fat and grease is revolting to me. I am also the only vegetarian out of the 4 of us if this is relevant at all.

My parents really did not like this even though I explained I did not want to touch all the fat and grease left over from the pork. They shook their heads at me and gave me their disappointed glare that I hate and told me how lazy I was. Mum would barely look at me. In about an hour I expect she will come into my room and tell me how awful I am for not completing the dishwasher and lecture me on my laziness.

So my question is - does she have a right to be this angry?

TL:Dr - didn't load up the dishwasher because did not want to touch meat, my parents are really unhappy about it.
