post partum anxiety
After giving birth, your hormones take a long time to truly normalize. Your body has been depleted of nutrients, and if you breastfed/are breastfeeding, that extends it. This is important because your ability to cope with stressors is dependent upon having stable hormone levels. If you're not stable, you get jolts of cortisol into your system, which eventually triggers the adrenaline behind an anxiety attack. Getting adequate rest, relaxing as often as possible, and doing other things to generally lower your stress levels, will help tremendously, even if it's not directly related to the situation you're in. Make sure you're eating well, which is much easier said than done, coming from someone who did a lot of emotional eating during my postpartum period.
For me, I ended up getting anxiety attacks every single day as the sun went down. Somehow it was related to the fading light, and would last well into the night. I frequently cried myself to sleep and would panic about anything. My ability to cope with any stress disappeared. It was gone by morning. I finally found out it was because I had very low progesterone levels, which was amplified by eating too many grains and having low vitamin D levels. The pregnancy exacerbated every condition I had previously by further depleting my low nutrient stores.
Basically you just need to support your overall health to slowly get back to normal functioning. Good luck finding a doctor who takes hormone levels seriously if choose to go that route - most of them will just tell you there's nothing wrong and hand you another prescription for anti-depressants because it's easier than educating themselves about the intricacies of subclinical readings. I've had good success in working with a classical homeopathic doctor to treat the root of the problem, but I suggest doing a bit of reading on what homeopathy does first.
