Baby shower thank you cards

Ugh so my little one is almost a year old now and we had her baby shower when she was 2 weeks old. I had started writing my thank you cards right after the event but never got around to finishing them. I do have my reasons for not getting them all done tho. First of all we had a ton of people there from both sides of our families, so that made for writing about 50 cards total. Then my boyfriend said he wasn’t going to write cards for his side as he thought it was pointless which left me to write them all. I’ve been home parenting my baby and my older child which makes it hard to find any free time and lastly I’ve always had problems finishing tasks for as far as I can remember. I’m pretty sure I have ADD undiagnosed haha but I struggle super hard with finishing things. Therefore my thank you cards are about half way done and I have no idea how to get them to everyone. But it’s almost been a whole year since the shower. I feel like a horrible person for not sending them out yet 😩
