I can’t hold a job

I can’t hold a job I’m no call no showing today at a new job cause they said I’d work the counter and ask people what they want I’m down a bunch of money and need this shit so bad. All jobs end with me being put in a uncomfortable position that makes me freak out mentally and quit. I have blocks and try not to follow through with the stutter but it impedes a lot of my vocabulary in the moment and I may seem dull and unfriendly when I want to be the opposite. This is embarrassing cause my family n gf are relying on me to hold a job so we can move out. I’m folding so hard. Social anxiety due to this shit has haunted me for all my life. When will it stop how do I live comfortably. I can’t accept my stutter and just stutter
