What do you mean by the right person? The person you want to be, or think you are or were? Or the person the "world" wants you to be? Or something else?

One thing that's probably way too little that I feel compelled to say is a para-phrased quote that I love from one of my favorite tv shows, Leverage: No one knows who they are, life just rips it out of them.

It's okay to not know, to be confused, to feel things that aren't positive or you think are "bad". Don't expect to 100% know yourself, but focus on learning about yourself and making the best decisions you can and nurturing yourself with positive stuff so maybe more positive will come out.

You should probably get that therapy to rule out mental illnesses that could be being treated. Some not knowing ourselves is normal, while some could be more than what is normal, could be a sign of something else, and should be treated.
