I’m so stressed

I’ve started this new job and I always feel dumb there and overwhelmed I’ve only been there for 4 days and I keep messing up the ice cream machine and etc ..😭 I have super bad anxiety with the general public too .. and I also have to go to community college so I can transfer to a 4 year but I don’t have a liscense yet because I get a little scared of driving ( I have a permit tho)
