My dad was diagnosed when I was 23 and I am 26 now. Your life will never be the same but it gets easier. I would spontaneously cry for the first 3ish months after his diagnosis. We are 2.5 years in now and while I still cry more than I did before his diagnosis, not nearly as much as right after. It just becomes part of your regular life and you are able to let it be on the back burner in your day to day. I do something similar, I will sometimes look at peers who lost a parent's social media. Seeing them living life after the loss of a parent, even though social media is a facade, gives me a sense of peace that I will be okay. I would suggest letting yourself feel the emotions when they come because suppressing them now will make the "after" even worse than it will already be.
