Don’t know what to do 😥

Recently I havent been feeling like myself.. I’ve been feeling unhappy and not being in the mental state. I’m currently in a relationship... its not my boyfriend that is causing this I just feel lost 😕 I don’t know if to either take a break to find myself and to mentally heal myself and to re-find myself or to continue on with my relationship?? Overall it’s just taking a toll on me.
