Mitzvah of Tallis Katan

I know it is a positive commandment to wear a tallis katan all day. But is it a violation of a negative commandment to fail to do so? Personally I find it physically uncomfortable to wear this garment. It makes me feel constrained. I don’t mind putting it on just for prayers, which is what I‘ve been doing lately, but I cannot stand wearing it all day. I know that as a rabbi, you will probably tell me that it is a mitzvah, and I should fulfill this mitzvah, regardless of any discomfort it may bring. But that is just too much suffering for me and I can’t take it. I found that when I tried to wear the garment all day, I grew to loathe it, leading me to not using it at all for almost a year. Then I tried putting it on for morning prayer only, and I found I could tolerate it much better.
