Hello there. I am sorry you are having such a rough time! I am not a psychiatrist, but I am a mental health therapist and the first thing I would say is that you are moving kind of fast. Zoloft is a drug classified as an SSRI (Selective Serotonin Reuptake Inhibitor). They take a couple of weeks to really metabolize into your system and even longer to wean off. Folks can have some very dangerous effects doing it too quickly, commonly know as "serotonin withdrawl". It can make you feel exactly like you are describing. I have had some clients check themselves into the hospital because they did this so fast. My best advice to you is to talk to your doctor (I ALWAYS suggest a psychiatrist because frankly I think other physicians have NO business prescribing a psychotropic medication) and go off the drug SLOWLY. If I remember correctly, a therapeutic dose of Zoloft is 150 mg. (I might be remembering wrong here). So if youare taking 300 mg, go down to 250 for a couple of weeks and then to 150 for a couple of weeks and then down to 50 for a couple of weeks. Still be prepared for some withdrawl symptoms, but not nearly as bad if you do this slowly, get plenty of sunshine and exercise and have lots of support.
Hope this is helpful!
ANother P.S.- I strongly feel like OB/GYN's are passing out SSRI's waaaaay tooo quickly. True PPD is serious but really a patient shold wait 5 to 6 weeks before going on such a medication to see if things really get better. There is other Post Partum Support available in the area (as I needed a bit of support myself)!
Take care!
