Rewatched the show I need the movie NOW

So I just finished re-watching the show and I’m thinking about where the show ends compared to the comics and I’m like God I hope we don’t lose too much in the movie. It makes me so sad that we only got three seasons instead of four even though Alice herself said to tell the entire story she/they would need four seasons. I don’t know I just it felt so cozy and I miss my heartstopper so much. It’s been since season three came out that I’ve seen/read the comics and I just don’t know how I’m gonna feel after it’s over
