Everyone forgot Mother's Day

I have 4 kids. Two daughters, 17 and 8. Two sons 14 and 6 months. Me and my husband have been together 21 years. Yesterday no one remembered Mother's day. It felt like people forgot I was there. My 14 was crashing out all day. He has 0 emotional regulation. Whenever anything goes wrong he crashes out and then says he wants to hurt himself. He has a fallen out with a friend and that's what that was over. I was taking care of the baby. No one really acknowledged me. My husband is better at handling our son. I feel like my son listens to my husband better than me and my husband can reason with him better but he was just having a break down all day. My 17 year old wasn't making it better because when he said he wants to self harm she said "Then do it. Stop whining about it." So my husband was scolding her and I was just completely forgotten about. I told him today they got mothers day and he's saying we can celebrate it this weekend but I feel like it won't be the same....
