I'm currently unable to be medicated for the various things that are wrong with me. 
I have severe nearly debilitating anxiety but I'm 20 years old, no license, and I still live with my parents who are demanding I get a job ASAP. (Which I realize is reasonable)

I got my first ever job when I was hired as a cashier back in October but I quit on my third day after having a panic attack at the register. I thought forcing myself to get out there would help me but it turns out that being a cashier is way too out of my comfort zone as of right now. I know this is pathetic but since I graduated high school (my college was done entirely online) I've spent almost every day lying in bed, constantly feeling fatigued if I leave my room for even a short while. Transitioning to a job would be extremely difficult and uncomfortable for me. 

TL;DR: I guess what I'm asking is: without medication, how can I, if possible, bring myself to finally work? Are there any techniques to help ground me when I'm anxious (which feels like all the time) or any tips on how to leave the house without becoming so immediately exhausted? I was planning on maybe applying as a silverware roller at a restaurant, as I don't know anything else that I could realistically do.

Sorry if this post is stupid. I'm leading a completely useless life at the moment and I'm scared it'll never be any different.
