Time for dr?

I’m trying really hard to not go on meds this time. (Had PPD after my other two pregnancies) I’d love to just be myself for once. I don’t like Zoloft and I don’t trust other medications since I’m breastfeeding. But lately I’ve been feeling off. I know not wanting meds can be a symptom of PPD so with that in mind I took a look at PPD symptoms and circled the ones I feel describe me. Idk if I’m just in a funk or if this is PPD or if I’m just being a big baby. The biggest thing for me right now is this inner exhaustion. I feel overwhelmed and like it’s not going to get any better and while I don’t regret having my third child because I love her to pieces, but I’m wondering what the hell I got myself into lol I feel like I can’t be consistent with my two year old because it’s too damn exhausting, like I can’t put effort into my six year old to figure out her ADHD and what works for her because it’s just too much, and idk if this just my new mom life or something more?
