For me I found that switching back to using my nails every now and then, at least let me produce something that sounded reasonably musical and helped me to not get sick of the whole thing, at the same time persevering using picks usually for picking exercises or scales etc, eventually getting the hang of it.
At first picks can feel like shovels strapped to your fingers, right enuff when I bought my first couple, the guy I bought them from did say to me - Here's two shovels, take your pick.
