Please dont judge me to hard

I know im gonna catch a bunch of heat for this but i really need to vent and my family and friends would hate me if i said this out loud so id rather be hated by strangers than loved ones. So i had my son 2 months ago and for the first few weeks i was in heaven! I loved everything about taking care of him and was completely in love! But as the weeks went by i slowly started feeling more distant from him and that feeling of bliss started to go away. Now i almost hate being a mom and i cant help but feel iv made a huge mistake. I still love him to death but im miserable everyday. I constantly feel stressed and angery. I cant help but feel maybe he would be better off with someone else. Im just overwhelmed and miss my old life. I know im a bad mother but i i do love my son i just dont know what to do anymore
