I have NO IDEA why it's doing this! It seems that when my comments get either to a specific length (or I type a certain symbol maybe) whatever comes after that point, is cut off. I don't know why it does this and I would love to know how to fix/avoid it! HELP!

HTML symbols can do funny things like that. Try and avoind the slashes:
/ or \

Also the triangular brackets:
> or <
