I enjoy working alone, did I pick the wrong career?

I think you chose the wrong bootcamp. Or perhaps if you can get by for the time being and then you'll be fine as a lonely SWE later on. So communication is critical but that doesn't have to be live 1-1 communication. It can be written communication too that's async. I would also consider this when choosing a company to work at. Automattic is a company that is entirely async and the interview process is also async and chat based! I know a lot of engineers who are super introverted and don't talk to anyone and are paid $2M a year because they have tremendous impact. That said, it's rarer because you can have a lot of impact by working with people and talking to them. Having an impact as a lonely SWE at a company-wide level is harder. But yeah, you'll be just fine, just consider it when choosing a job so you end up at the right company. Bootcamp grads have such a hard time finding jobs maybe it's something you'll look for in your 2nd job.
