Should I just delete my account and create a new one so I can actually create posts again?

I've been on reddit for a couple of months with absolutely 0 issues, however, one of my comments somehow got a bunch of downvotes (a group of trolls?) and now I have -100 comment karma. It's taken me a couple of months just to get to the point where I can post on certain subreddits, but with -100 karma it'll take forever to get back to that point.

Anyways, if I delete this account (I don't really want to) and create a new one, are there any issues that may arise? Thanks
