I am a 20 male and I have been diagnosed with depression and anxiety, am I taking the wrong Meds?

I am a 20 male Been diagnosed with depression and anxiety
Originally prescribed 10mg citalopram and 10mg propranolol
Doctor now changed my prescription to sertraline 50mg and propranolol 80mg extended release
I went back to say these arnt effective and now he has changed my script to sertraline 100mg but these are helping slightly however I still think I’m on the wrong medication as I feel I have bipolar –

I get really depressed which the antidepressant have heped with big style, however I get periods of highs where I get dizzy feel on edge feel sweaty I usually just eat something and wait for it too pass but it can last hours, I feel I could have bipolar and am taking the wrong Meds could I be right?
