Plenty of expats who are happy. The miserable ones tend to congregate online, don’t let it affect you!
I’m French and I moved to the UK after my studies, love it there, and then moved to Spain where I’ve been living since. Love it here to.
Spain and the UK are real places with their challenges, but if you can sort out a job for yourself and a good relationship (for those who want to be in a couple), then I’d say the rest is up to you as much as it would be in any other country.
If you can embrace the new places, being out of your comfort zone and trying to figure out the place, you’ll have a good time.
Moving abroad and writing new chapters of my life in foreign land has been the most important thing I have ever done for my personal development. I think anyone who’s remotely interested in trying it should go for it.
Honestly, you’ve done the hardest part already: you speak French and you’ve been there multiple times. I wish you all the best for your move :) Bonne chance pour le déménagement!
You’ll be fine, give it some time. That’s the reality of settling in a new culture, it can be quite alienating at first. Embrace being the foreigner, I a few months you’ll have learn plenty of things! Well done on the move 👌
