So sorry you have been under stress. Reading is a great release, escape, and joy. But it's so true that what works for one will not work for another! I would recommend "tasting" quite a few books if you can. A library is a great resource. You can rent regular, ebooks, or audio books and don't have to commit. Try a chapter or two and if it doesn't speak to you in this moment, let it go with no regrets and go on to what does amuse, console, or enrich your mind and heart.
I'm a constant reader but often read what most people would consider difficult books, both in terms of subject matter and style. (Recent example, The Red Parts by Maggie Nelson). And, yes, Canadian books, too -- re-reading Alice Munro's Runaway right now.
For travel, is there a particular place you dream of going someday? Or where your mind takes you recently in imagination? If so, maybe I can think of the right author.
If you want to laugh and laugh, you can't do better than silly British inter-war comedies like those of PG Wodehouse. Silly slapstick and witty wordplay. I also love Georgette Heyer's Regency romances for that -- The Grand Sophy is hilarious.
