My social anxiety has increased and I feel so frusturated with myself I just want to take something to "take the edge" off. Im tired of internally freaking out and running (literally) away from uncomfortable social situations.

So do you believe in meds or no? If not, whats the other alternative?

you've probably heard it before but you just have to confront the situation - meds dont solve the underlying problem.
I have had SAD my whole life and was on atleast 6 different meds over four years.
That whole time I rarely went anywhere. Stopped taking them, FORCED myself to confront scary social situations and improved slowly. You dont want to have to rely on a tablet your whole life just to function in social situations.
I hope you find a way to get over this. Good luck )

Assuming you have spoken to a doctor & so prescribed meds. then yes I would say you should take it. If you are literally freaking & running then yes you need some help coping. An alternative would be some form of thearapy, but my thoughts are you should discuss all these questions with your doctor.
