Anxiety vs postpartum anxiety

Lately I am getting more and more anxious. It was been going on since I had my second child, 2 years ago. Lately I have been feeling anxious over nothing. I have no idea why, I just feel anxious and my feet sweat. I feel stressed when doing nothing. My anxiety is not centred around something happening to my newest baby (4 months old). But I often flinch or groan out loud when my older children are doing something simple like walking down the stairs and I can see how they might fall and get severely hurt.

I have been having some health issues since I had my daughter. Tingling in limbs and face, headaches, dizziness. Which just makes me more anxious thinking I’m dying, and going to leave my 3 children without a mom.

Is this anxiety or is this postpartum anxiety? I’m breastfeeding so not really wanting to take something for it. I love breastfeeding, and don’t want to stop. But I’m concerned it will get worse and worse.
