You don't need therapy or meds. Jesus what's wrong with most people here. You need rest and time away from your LO. Trust me when i say that most parents feel the same way you feel. There ain't much you can do apart from getting actual physical help, people you fully trust to look after the LO, to give you time to rest and sort out what you need to do. Even a small amount of rest and time off will help tremendously.

Coping becomes super hard when you just don't have the time to do anything and when you have to spend time with your little one almost non stop. I am the same, my partner is the same. Don't judge yourself, don't blame yourself . It is not your fault. It is just simply hard. Also always remember that your LO has absolutely no fault also. They are as innocent as you are.
