How to move on from your favourite manga?

Im sorry for posting this here (I have nowhere to go) but I just want someone to cry with me , rant with me, give any thoughts about it, give me something positive vibes, or give me advice please~

My favourite manga, Haikyuu, just ended, its the first time I feel so sad after completing a manga, I know its happy ending and I should not be over reacting like this but it really hurts when I remember all those memories and that feeling I would not anymore wait for any chapters of it

I would love to read any thoughts you have for haikyuu
