Crippling Social Anxiety And Paranoia. Need Urgent Advise

Hello all, I have had social anxiety my entire life and I just don't know what to do anymore. I am soon to turn 23 and I still cannot work. The hardest thing ever is being out of my House. I get completely overwhelmed with anxiety and paranoia, thinking everyone is looking at me and judging me based on my appearance, body language or anything. I have tried rational thoughts, medication, therapy, meditation and all you could think of, but I'm at a dead end. My therapist says he doesn't know what to do next because I am making such slow progress. I get a red face, watery eyes, fast heart, shaking etc when I am walking down the street for instance, and if I am having a conversation with someone, I'll be so focused on myself and completely freaking out inside that I just want to run away and get out of there. I am eager to go 110% from now on with my exposure and therapy, but its so scary and overwhelming having to practice your worst fear every single day. Is there a specific medication that is used to treat social anxiety? I have been on Mirtazapine, Fluoxetine, Citalopram and tried some Benzo's, but they are always just temporary. I am currently on 20mg Fluxoetine and it is helping me sleep, but my anxiety is as high as its ever been. I can't think of anything thats ever helped. IF anyone has any advise on how I could move forward I would really appreciate it.

U have a low self esteem…u need to trust ur self and be brave.. It will not happen in one day. It is something that u have to practice.. I am taking medication that reduce. Fear.. My cardiologist prescribed it for me.. Escitalopram unicorn 10..
