Please Help – Science Fiction Saga Recommendations

I know this might have been asked many times, but I read through the threads and am looking for help on something based on my favorites. I've been going through a very rough time mentally for the past few years. One of the only things that has made me able to escape and feel excited again is reading my favorite series.

A few of my favorite series are as follows:

• Culture Series – I don't generally re-read books but I've read this entire series 3 times now in the past 20 years, I save it for when I'm really down and read it again every 5 years or so, I think about the books/characters/ideas often, this is my favorite set of books of all time out of thousands of fiction/non fiction and I can't really explain why but it is.

• Three body problem – the ideas in this book and the page turning, what's going to happen next are amazing here. It fires up my imagination more than most.

• The Expanse – There's a few parts of this series I am not fond of and skip over on re-reads but overall it's a great escape and adventure

• Ancillary Justice – I just liked it, even though the author doesn't explore too many crazy concepts

• Takeshi Kovacs (altered carbon) – just love the violence and ideas and adventure/ideas

I could list more but with this list hopefully someone can suggest a few books, ideally a long series I've somehow missed out on. My problem is that I only like what I like, and I'll try hard to get into something but if it's not "my thing" I give up. For example I tried to read children of time 4-5 times and never finished the first book 🙁

I would be eternally grateful for any suggestions, I will look into them and give them all a chance, thanks!
