I need advice!

The past few months I have had ZERO energy. I sleep 8-9 hours a night, no interruptions. I wake up exhausted, and with no energy. I force myself to fix breakfast for my kids and pack my husband's lunch. But most of my time is spend sitting on the couch. I have no energy to take my kids outside to play or even go in their room to play. I feel like a horrible mom because of it, but idk what to do! Please help 😞
