I was diagnosed with postpartum anxiety when i was about 2 weeks pp, However i wanted to try to resolve it myself. Exercise, therapy etc.

I started working out etc, im 5 months pp now and I feel like the anxiety turned into depression. Not like i want to kill myself but im angry all the time, no motivation, lately i just want to cry but i can't . I get so annoyed or irritated so fast. everything everyone does annoys the shit out of me.

It's not like this all the time, its at its worse when im tired, but i still feel it there a little bit on my "good" days.

I have a prescription in my counter for zoloft, that my obgyn prescribe me back when i was 2 weeks pp. My question is,

Should i just start taking it or go see a my therapist or doctor first?

My therapist wont prescribe me anything, im not even sure she'll tell me if im depressed or just overworked.
