Starting to hate being a parent

I’m so overwhelmed right now my husband is deployed for 6 months i have a 10 week old and almost a 2 year old and i moved back home while my husband is deployed but starting to feel like it was a bad idea. My two year old gets into Everything at my parents house he conveniently does it when I’m always busy with the baby. He messes with the outlets keeps unplugging and plugging in the Christmas tree takes all the food out of the pantry gets into other peoples bedrooms and messes them up. Thank god i stop breastfeeding or i would seriously lose my mind. My parents work all day and i don’t have much help from them when they’re home anyways. When i ask my sister to help with something like putting my kids shoes on if we are about to go somewhere together she always says they’re not my kids so i always feel bad asking for help because i know they’re my responsibility. My parents have two big dogs that will constantly bark if they need to go outside so i have to take them outside while still dealing with two kids. I’m just really stressed out right now having to take care of two kids on my own.
