My son is almost 2, I never stopped having PPD.

..and now I'm pregnant again. I never feel good enough, which makes me worse. I do what I can, but my in-laws don't seem to notice, they expect more. My almost 2 year old son is a handful and I'm 11 weeks pregnant on top of it. I was trying to sign up for beauty school to get somewhere in life but my SO doesn't help out much at home (great with the 2 year old though) so basically I'd be in school 40 hours a week, clean the house all the time, while being pregnant and exhausted and with a 2 year old. It doesn't seem reasonable to me, but his family acts like I should have 2 jobs and go to school and be fine. I'm overwhelmed and all I do is stay home and clean! I feel worthless and less than everyone. I can't get ahead at all. I'm tired and sad and alone and everything feels so hard. I can't bond with my 2 year old.. He's two! It should be over! And now I'm pregnant again? I'm totally lost. I feel so afraid I'll never stop, never get ahead, forever be less than..
