I feel your pain. I am also left-handed and during school times switched pen nibs every other month since they kept deteriorating. And I never quite got the hang of avoiding smearing. I switched to writing almost exclusively on tablets a few years ago and it's so much better for me. I can't quite put into words how much of a difference it makes for me. Smearing is a non-issue and the pen glides fine either way on a glass surface. There are some other benefits as well: I can no longer loose my notes and I'm a lot better about filing them away neatly digitally than I am with physical notes, but I suppose that might be a very personal thing. Having them indexed occasionally comes in handy as well. I went from a Surface to an iPad Pro and vastly prefer the latter. If you haven't yet I would recommend giving it a try. These days even the normal $329 iPad supports the Apple Pencil and provides incredible value in my opinion.
