I'm worthless because im not really able to walk. I actually collapsed at work because my sciatica flared up so bad it's crippled me

It hurts so damn bad i can't even walk without screaming in pain. Im beyond worthless because i can't do anything. Im unable to move my left foot or leg because if i do it radiates pain so badly i want to cry. Im sitting in my car and it's still shooting pain everywhere and it hurts to breathe. I got no idea how im gonna get out of my car and into the house because it hurt to sit down
