It depends on the med and your body's reaction to it.
But for me, without meds I am a complete mess.
A few months ago one of my meds started loosing it's effect on me. It made me so so sad because on the max dose, it had been my miracle med (Zoloft) for three years. But since I didn't change meds in time, I had a major depressive episode that put me back in the hospital.

Meds certainly are not a quick fix it all, and usually a combination of meds and therapy work the best. But the right dose of the right med should definitely help get you back on your feet.

Good luck! Finding the right med and /or meds combo can be frustrating at times.
