Should I drop a subject?

I've been having troubles completing work for all the 4 subjects I took, partly because my lack of organisation and procrastination. I took eng lit because I seen it as a back up if my grades for other subjects weren't too great, and I thought I would come to like it ( I like English, but I hate writing essays). I am worried now that it might dragged my grades for other subjects down and I was hoping that dropping it would lighten my workload and stuff. Is it too early to drop? Should I persevere and try to stop procrastinating so much (also any tips to stop this?)
