tired 24/7

for the past week and a half i’ve been EXTREMELY tired. i’ll get my 8 hours of sleep wake up feeling drained and not have any energy. my cleaning has been slacking bc all i went to do is sleep. i have no energy what so ever. i barely have enough energy to make my daughter food that’s about it. it takes my body so long to fully wake up. any tips on why i’m like this? what can help me?
