10 months into my first job (Software Developer) and I am still so unbelievably bad at it, it's destroying me. What do I do?

I'll try to keep it short. Graduated out of a good college and got my first job at a good company. When I passed out of college, I was full of confidence because I was a bright student (not top but still pretty good) and thought I would ace the job. 10 months in and I am still so insanely bad at it, I have completely lost all my confidence and I can't even get simple tasks done anymore. Now I bunk a lot and have a very poor work ethic. I want to quit but I don't have enough backup funds to last me even a month. Looking for a new job but with the now ever lingering self doubt that what if I am just as bad at the next one. I just hate getting up in the morning now and I am so scared all the time. What do I do? Any advice would be good! Thanks!
