I need help

My son is now 8 months old and I've been suffering from postpartum depression, I have a bad history with depression so I knew this would happen. I have constant suicidal thoughts but I never actually on then because I'm a single mom and my son is my world, I couldn't cause myself the pain of leaving him, he doesn't deserve that much less a depressed mother.

I don't have insurance so I haven't been to the doctor ever since my 6week checkup when I also had nexplanon inserted and it has made my depression significantly worse to the point I've thought of just cutting it out myself because I can't afford the visit fee. That visit I explained to the doctor I had been depressed but she had to give me anxiety pills because it's always been hard to prescribe antidepressants to me because I am alergic to Prozac, an antidepressant I took as a teenager, and many antidepressants have the same ingredients. Is there any kind of clinic I can get into without insurance that can prescribe me something. I'm suffering so much.
