my struggle with side effects

Currently suffering from side effects. Been crying and groaning in pain for the past hour. If I could I would want to rip out my whole stomach and throat so all this pain would go away. I haven't been on my meds (Zoloft: treatment for my depression and anxiety) for a few days, and now that I'm trying get back on them they're acting crazy in my body. I've even tried to force myself to throw up and all I have is just stomach acid mixed with saliva. I just want this to stop. Please share your thoughts and experience with side effects. How do you deal with it? I used to use an binaural sound app to help with pain relief, but somehow it's not working this time. Probably because I haven't been using it for a long time, not quite sure. My head hurts, my chest is tight, my throat is tight, I can't breathe, my intestines feels like it's cramping and I want to throw up. Somebody help please.
