Warning: angst, character death
Summary: you can't cope with the death of your father so you go back in time, much to the protest of the avengers, and try to reverse his death but what happens is just as bad as what you wanted to reverse

It had been 12 days, 4 hours and 32 minutes since you had lost your lifeline. Since you had watched your father, earths best defender, defeat thanos one last time but it had cost him his life. Ever since then, you lived with your step mother (who is like your real mother), pepper and your half sister Morgan.
You were sitting in your room, reading a book and cuddling with your cat, Salem. When you were about to flip the page, there was a knock on the door. You sighed and put your bookmark in your book, closing it and straightening your legs and sitting up. "Come in." Pepper poked her head in and gave you a smile. "Hey, dinner is ready." You smiled. "Ok, i'll be down in a minute." She smiled at you again and shut the door. You set the book down on the desk and lingered for a moment, looking at a picture of your father. You smiled and touched the photo. "I promise you, we'll see each other again."

You had been thinking for a while on how to get your father back. You would stay up late at night, run on 3 hours of sleep and a coffee or two.
You were down in his old lab and found his notes for time travel from about a month ago. You skimmed through the notes and found out that the time travel place was at the compound.
You ran down to talk to pepper and she sighed. "I miss him as much as you do but please, don't go back in time." You sighed and agreed.
One day, you guys visited the avengers compound and pepper had told them how you were trying to do. Wanda pulled you aside. "Please, don't. Your father would kill you. He died to make the world a better place. Please don't." You sighed and walked away. Later, that night, you snuck down and arrived at the place your father and the avengers were almost a month ago when they went back in time to save the world. You started the machine and time traveled. Wanda heard the machine and ran down to see you disappear on the machine. She sighed and rubbed her face

You had arrived at the time before your father had snapped. He had just taken the stones from thanos. He was preparing to say his last words when you ran over and knocked him down. "Y/n? What are you doing here?!" You took the stones and stood up. "Saving your life." You put the stones in and looked at thanos. "Good luck in hell, you purple ballsack." Then you snapped. Thanos and his minons all disappeared. Tony looked over to you and saw you leaning next to some shrapnel, barely hanging on. He ran over, pepper followed behind him. "Hey kiddo. Hang on, we'll get you some help." You smiled at him, weakly. "love you 3000" He smiled and tears appeared in his eyes. Your body went limp and he knew you had gone.
All the avengers behind him kneeled. Tony had wrapped his arms around you in a hug.
Tony set up a funeral for you when you guys got back to his house. He walked back into the house and cuddled Morgan. "Dad, when is sissy coming back?" Tony held back tears. "Not for a while. But she'll be in our hearts forever." Morgan hugged him and looked at the picture of you all in the corner. "We love her 3000. Do you want some cheeseburgers?"
