Help! I'm a run-on sentence and I need your help

Help! I'm a run-on sentence that doesn't know how to end in the right way. It's because all of my ideas seem connected. Even though my writing doesn't have any punctuation or even any capital letters, I think I will see if my students can fix this piece of writing. This isn't really an essay or anything particular. It just feels like my brain is a faucet that I can't turn off. I really hate it when this happens, because it's so frustrating to me when other people don't seem to struggle too much knowing how to avoid run-on sentences. Don't even get me started on sentence fragments, because our minds think in fragments not in complete thoughts. This makes me want to distrust writing. Do you know what I mean?
