Severe social anxiety: which antidepressant?

Hello everyone,

I have severe social anxiety, and I don’t know which one to take between:

• Paroxetine (Paxil): It seems to be the strongest one for this condition, but I’ve read that it causes weight gain. As I’m already overweight, this scares me.

• Sertraline (Zoloft): It seems to be commonly prescribed, but what about its effectiveness compared to Paroxetine?

• Escitalopram (Lexapro): It seems this one has fewer side effects, but what about its effectiveness?

• Venlafaxine XR (Effexor XR): It seems to be the strongest one (maybe even stronger than Paroxetine?) for depression, but what about its effectiveness for social anxiety?
