<human>: Can you provide a brief rundown of the text in within 3 sentences?

I started trying to lose weight at the end of February. I told my parents and they seemed alright with it, but my mom seems to not realize that she buys way too much food for the four of us (myself, parents and sister). We have TWO fridges and they are both completely full of leftovers and ice cream and all kinds of junk. The day after I told her my diet plans she cooked chocolate chip pancakes and my dad ordered pizza for dinner. She literally brings food to me every hour or so that I'm at home. My mom is a nurse so she's always telling me I'll be healthy if I just eat what she gives me but if I did that it would add up to about 3000 kcal per day and I'm trying to eat half that! She gets angry when I refuse food and when I asked her if I could cook for myself she just ignored me. 
My dad is also trying to lose weight but he eats whatever my mom makes and hasn't been successful. He never cooks, but on the weekends he always goes out for lunch, so my sisters and I usually do too. He doesn't have a plan and isn't really committed to it. 
I've lost 10 pounds (170 to 160) so far but it's been so hard and my mom has not been supportive at all despite her initial approval. My dad is proud of me and has gotten better about buying food for me (he will call and ask if I want anything instead of just assuming I do). 
What can I do to make this easier? I know it's not supposed to be easy but when my family was gone on vacation for a week (I couldn't go) it was SO much easier to eat less! Without my mom shoving food in my face constantly I ate a reasonable amount. I cooked and shopped for myself and it was the best week for my weight loss so far. How do I convince my parents, mom especially, to let me cook for myself? Or at least not give me all of the food she cooks.
<bot>: My parents buy too much food and it's hard to not eat it when it's in my face. Do I just deal with it or can I convince them to stop?
