Perhaps a better question is, "Does this area of technology suit you?" Don't give up without a fight, and don't assume "being bad" at what you're doing now means you can't improve or do better elsewhere.

It can take a long time to uncover your strengths--decades, certainly. But stay confident that you will eventually find them. And if you don't find them, then make them.

Find stories about people you admire, who did great things. Learn what they did and how they did it. You can draw inspiration from their experiences. You can draw on their strength to support your own.

Best of luck to you, and know you're not alone.

Hope ya feel better --
