Am I showing signs of PPD

I’m not sure if this is just normal hormones or if something is wrong.

My daughter was born a little over 2 weeks ago. I have a 2 1/2 year old son that I can’t quit being angry with. I don’t know if it’s stress because he won’t listen and is acting out more or if I’m just losing my cool a lot easier. I feel resentful towards him and like we no longer have a bond. I hate feeling that way because I love him so very much.

It’s not just him that makes me angry, it’s everything. Just everything is setting me off, this isn’t normal for me. It usually takes a lot to frustrate me. In NO WAY have I thought about harming myself or my children. Most of my frustration is my toddler and spouse. I know my toddler is most likely acting out because there is a new baby. I’m trying to understand, but I can’t seem to control my anger. I don’t want to talk to anyone about it because I don’t want it to be dismissed because I know this isn’t normal for me. I do feel kinda sad every now and then, but it’s mostly the anger that’s getting me.
