Self doubt  is absolutely ruining my life and preventing me from doing anything. I’m 21 and I never had a job. I’ve been wanting to have a job since high school. I would fill out an application, get a call back to interview and I would never respond. I’m not even nervous about the interview it’s moreover me thinking I’m too incapable and incompetent to hold down a job. I think a lot of this all stems from things that happened to me back in middle school and messages that my parents sent me during that time period and prior. It’s horrendous. I can’t keep living like this. I’ll see an internship that suits all my interests and then I’m like “but what if you mess up”, “what if you don’t please your boss”, “what if you don’t impress your boss” , “what if you do something stupid” . The thing is that chances are these things will happen. It’s part of being human, and it is not an attack of myself. However, it’s like I’m frozen. I’m so frustrated because living like this is going to fuck up my life. 
Then also a lot of this- I’ll mention to my parents about a potential job I’m interested in and they will be like “oh is it something you can do” then I mean back in middle school, I always had teachers underestimating me and I think this caused me to question myself even more. Idk 🤷‍♀️ but it needs to change
