Third pregnancy

This pregnancy so far has been horrible I feel like I have the flu and raising two kids and watching my niece 5 days a week on top of it do any other momma have any tips or tricks to feeling better having some energy to clean the house some and even shower ?.. I’m beginning to feel like a failure as a mom and wife due to me not being able to cook clean laundry and homework and play with my kids as I normally do thanks for listening just needed somewhere to vent and possibly get some tricks on shaking all this I’m miserable
