Never fear! "git rebase" isn't nearly as dangerous as many have been led to believe... unless you start rebasing things you've already published/pushed elsewhere. In that case you need to be very proactive about notifying everyone who could possibly have checked out your branch, etc. Otherwise: it certainly takes a little getting used to, but I find a little one-on-one "mini-mentoring" others with the first few rebases helps them immensely, so if you have someone who can help you in person it might be a lot easier to get comfortable with the process that way.
