Very very intense mood swings 3 days pp?

Is this normal at all? Maybe not as intense as mine.. but i also have depression. I’ll have parts of the day where I think this newborn stage is never going to end and my milk will never come in and I can’t be a parent I don’t know how and I want to give up.. then other times I feel perfectly fine and happy and love taking care of my baby.. probably just all these whacky hormones
