It's fine to vent; it's half of what the internet is for. Since the internet is also for acting like you know what you are talking about and offering unsolicited advice, I'll also drop some here. Feel free to ignore it, and I hope you situation gets better, either at your current job or a new one. I won't speak too much to your work skills, because I don't know you; but feeling like and worrying that you're terrible at your job is a pretty normal experience. You pretty much have to rely on whether other people think you are doing a good job because people in general are garbage at judging their own skill. It's pretty hard to tell the difference between "I think I'm doing poorly and am" and "I think I'm doing poorly and am actually doing fine", without a lot of feedback from people you trust (ideally, your coworkers). If your coworkers think you're doing fine, well, you can't stop worrying about it, but you'll at least have some evidence against your feelings; if your coworkers think that you're under-performing, they might at least be able to offer some advice on how to do better. The burnout advice I have to give is in three parts: first, focus on making some small, incremental progress every day; second, avoid the temptation to overwork; third, make sure to invest time in your life outside of work. The first is both about positive thinking and also about developing good work habits. The second is because it doesn't usually work (you end up doing less with more time, which is even more depressing than feeling like you aren't getting enough done in 8 hours). The third is because you will feel better and be more resilient if your entire identity isn't invested in your job. It's easier to both to avoid burnout and to recover from it when it does happen if your job is only one part of your life.
