Coping with PPD

I normally get ppd but try and cope on my own. This time my doc wanted to see me at 2 weeks pp to check in and see how I was and I felt great! For the first time in my 4 births I was not feeling ppd, then the next week it hit me and lasted the whole week pretty bad. Some how I picked myself up and have been coping ok since, some days are better than most. Today I went for my 6 week pp check in and I told my doctor that it hit me at 3 weeks pp. I started crying during the visit and she recommended I get on Zoloft or see a therapist. I’ve never seen a therapist and don’t want to talk to anyone about it, I don’t see how that would help me. So I agreed to trying the medication but am hesitant since it passes through to milk and I’m ebf. I don’t want the medicine to affect my supply or my baby, but I have 4 kids, am homeschooling 3 and taking care of a new born, and will be returning to work in2 weeks. Work will probably be from home since that’s how it’s been since the shut down in March. I don’t really want to take the medicine but I’m losing my self again and I don’t know what to do. It’s hard to talk or go see friends since all this covid stuff. My only 2 friends haven’t been doing that great at being safe and I’m not comfortable being around them. I feel like I have no one to talk to.
