Struggling is so hard

I've been on and off with not being in the best head space.  I get mood swings where I'm happy one minute, anxious the next or feeling frustrated or upset or tearful.   Been thinking that maybe I am bipolar but aren't so sure.  I know for sure that I have OCD and maybe some ptsd.   You see my dad is somewhat emotionally abusive at times.  He's bossy and can be quite controlling of me which I don't like.  He also gets frustrated or upset quite easily which is when he'll raise his voice and sometimes he'll also yell.
