I have been in DBT for two years. I'm about to graduate. I have also been diagnosed with BPD which is why they suggested I do it. I think can be helpful for anyone regardless of diagnosis. If anything-you'll learn some new techniques to get through hard times. I encourage you to step into it with an open mind. It can be confusing in the beginning but that's been the experience from everyone I know in it. Give it time.
Good luck!!!
