Is it too late for thank you cards??

First I want to say that I'm so sorry that you both had to go through so much for your wedding and shortly after. I know how much depression can make you feel like you can't even get out of bed, let alone do anything extra. My opinion is that thank you cards are better late than never. I wouldn't mind receiving a thank you note 4-5 months after the wedding, but I would mind never receiving one at all.

Not too late. Better late than never! I'd still send them now

Definitely go ahead and write/send them. I might even include a line about its lateness and apologize (you don't need to explain why, just "sorry this is late" kind of thing) but that's entirely up to you. Better to send them than have people irritated they didn't receive one at all.

I don't think its ever too late to express gratitude and technically I think they say proper etiquette is send them within the year. Send them now no explanation needed.

It is never too late for sending out thank you notes. Your guests will still appreciate a nice thank you note. We received a thank you note from a wedding we attend February 2020 and we received it like 8 months later. It was still a lovely gesture.

Definitely send them! My sister didn't do thank you cards for her wedding in May last year and a lot of people have been upset by it. They've all told me they'd have liked to get something, even if it was a generic one.

You're totally fine to send them now! I'm sure people will understand that with everything going on, you've been preoccupied.

I'm sorry for all that stress you had to go through before and after your wedding. Anyone's priorities would be all over the place after stuff like that, plus then the holidays would have been immediately after. If it's any consolation, though, I got married just two weeks before you did (Oct. 23rd), and we still haven't sent our thank-you notes! Literally every weekend we say we're going to do them, and yet it gets away from us. We have four boxes of brand-new thank-you notes sitting on a shelf in our dining room, where we can clearly see them. I believe others have said better late than never, and I wholeheartedly agree. In fact, you've motivated me to get mine done!
