I forgot

I forgot to pray at a certain time yesterday. We were gone all day and I didn't switch on my computer till we came home. My reminders are there. How could I forget? How could I forget. How could I forget. I feel so bad. I prayed before and after, but I wanted to pray during. Instead, I was at the mall thinking about which color leggings to buy, pink or orange. I thought about myself all day. I don't know why. Usually I pray for someone, somebody, at some point during the day. It just happens. And I think of one, so I think of another. How could I have had such an empty prayer day all day. What am I made of. What happened with my mind. This is the worst prayer time incident ever. I could just cry. I already did. Sigh. It didn't help.
