When should i seek help?

I have been thinking about therapy for the past 6 months. I was unhappy about my pregnancy because i didnt want another child and now im a few weeks pp and i love my new baby very much and would never harm or neglect the baby. I wish i had someone to talk to about everything but i dont want my family/friends(the 2 i have left)/or husband to think differently of me or judge me. My husband knows mostly how i feel but i know he doesnt like to hear it and i cant tell him everything without feeling guilty. Should i seek professional help or try talking to a friend first? I only have one friend who wouldnt judge but ive only seen her once since having the new baby and she prefers to talk about herself and didnt seem to listen to me.
