The main problem with antidepressants is many people believe falsely they should just be able to "snap out of it!" on their own: make their depression go away by will power alone. Usually that's not possible, so people who believe this can suffer greatly. And surprisingly often, it' a relative who shames you into stopping your medication, and then the depression comes back.
All that said, there are some things to know. Antidepressants are not 100% effective. Your doctor may need to try different types of antidepressant medications before finding the one that's right for you. And there's no guarantee that any of the choices will work, although usually you can find something.
Second, side effects can occur. SRI type antidepressants often have sexual side effects, like a loss of desire. Any of the more sedating antidepressants can cause weight gain that is sometimes severe. If you're gaining a lot of weight on this or any other medication, see your doctor. Something needs to change.
Third, you shouldn't stop them suddenly and may need to taper the dose over several weeks. SRI type antidepressants are especially likely to cause a withdrawal syndrome of feeling weird and having an upset stomach if stopped too quickly. But the larger risk is you decide to stop taking the medication on your own because you feel good, and then everything crashes down.
