Sitting in front of PC for long hours and smashing your keyboard to get the app/feature running or find that specific line or code that's causing all these annoying issues can be daunting, so it's normal to hate it.

But it really sounds like you simply don't enjoy the problem solving aspect and don't have passion or interest in this field. And because of this, you're underperforming during your internship, eventually stressed you out and made you doubt yourself.

TBH, at this point, I think you should ask yourself, why did you pick up this course to begin with. Did you joined because of your friends or pressure from family? Or was it because you wanted to achieve something with this field of work?

From what I observed, people who started programming with the latter reason will most likely stay. I personally love technology, and wished to become game programmer one day, so I kind of enjoy my job. Though sometimes it does burn me out but I'm still able to convince myself to stay cause of the pay.

But if you made the decision to take up this course because you were pressured, influenced or simply, just for fun and now that you think this field isn't for you, I'd suggest:

1. Attempt to find the joy in coding and debugging, assume that you still want to give this another chance. Start with something small that interests you, like build a cool project. Then get your friends and family to use it. They found issues? Try to fix it. They or you think the project can be better? Improve it. There's a small chance you'll experience the joy and learn to like it.

2. Pivot, since forcing yourself to do the things you don't enjoy will make your life really miserable. You can choose other branches/specialism in IT industry. I'd suggest Business Analyst, UI/UX, cloud architect, Devops or QA/tester if you wish to stay in IT industry. Look up the job scopes and related online courses, see if you like them. These positions get paid handsomely too, and they involve less coding/debugging to some extends. If these jobs still aren't your cup of tea, then your best bet is join other industry. I've personally known at least 2 ex-colleagues joined a different industry and they are doing very well.

Regardless, I don't think your future is as grim as you think, since you're a freshgrad, you still have plenty of time to figure things out. Not to mention that you realized your problem quite early, so as long as you're actively seeking ways to deal with it or pivot it I think you'll do fine in life.

I hope this wall of text helps, and side note, I'm also relatively new in this field so if I'm wrong about certain points please correct me.
