Postnatal depression or just a horrible person!!??

My son is 7 weeks old and I don't know if I have postnatal depression or if I'm just a horrible person! I feel like I don't want him at all. I miss the simple life without him and wish I had never had him. I keep looking at putting him up for adoption cause I just feel like I can't cope and that I don't want him! I don't know what to do 😢😢😢
