I think this is essentially true. If you do not enjoy programming, and have a hard time struggling with analyzing and solving problems (writing algorithms) then I do not think you will enjoy your work. I have seen plenty of developers that do not enjoy their work, and I would suggest that you avoid it, and stay with systems administration, or something else that you enjoy. There is a considerate amount of stress and pressure in the job anyway, as there are always critical deadlines and urgent problems, and if that is added to a general negative baseline of stress and discomfort, there is a high risk of real problems - like developing a real depression or occupational burnout.
