Worst mom on the planet

My son is 8 months old, when he was about 6 months old, he fell off of our bed. It's about 3 feet above ground so that was a far fall for him. We have drawers on our bed so luckily he landed on top of one that had clothes in it. This time, it wasn't open & he fell onto the floor which is hardwood flooring. I only have our son in our bed in the morning when my husband goes to work because his crib is in the living room & my husband turns all the lights on so he gives him to me in bed so that way he & I can continue to sleep until I get up for work. I honestly feel so sad & disappointed in myself for letting this happen again. Our son is fine, his cheek is a little red but I've checked everything they've said to check & everything looks good. Have any of you had this happen ? & how'd you get past feeling like you're the worst parent ever 😭😭😭😭😭
