Help I'm very worried about ssri side effects? Are they really dangerous?

Hardly ever. You'll read horror stories online, but actual danger is extremely rare. Common side effects include stomach upset, restlessness, ; impaired sexual function, all of which vary with dose, ; nearly always end right away when the ssri is stopped. Most ssris have to be decreased gradually when stopped to avoid withdrawal effects, again rarely a big deal, although some are very sensitive to this.
