Possible TW! Talk of anxiety and paranoia

I'm turning to reddit because I have some questions about the medications being prescribed to me.

First off, I understand that I definitely don't know nearly anything at all about psychiatric treatment or medications but I can't just need another opinion because I can't help but feel like my concerns are being dismissed by my provider.

I have struggled with depression all my life, and after moving to college approximately a year and a half ago, I have struggled with general anxiety and severe social anxiety. I have found myself unable to go into public and I even get paranoid thoughts when I am in public (feelings that I'm being watched, being followed, etc.) I know that they are just paranoid thoughts but I just can't shake the feeling. 

So, I started seeing a psychiatric NP in October. I told her everything above and more and she put me on sertraline 50mg once daily for depression, propranolol 10mg twice a day for anxiety (and high blood pressure,) and mirtazapine 15mg nightly for sleep. 

I took the medications as prescribed for about a moth before I had a follow up. I expressed to my NP that while I found the mirtazapine for sleep very helpful and effective, I didn't think the sertraline or propranolol were helpful at all as they didn't help ease any of the psychical or psychological symptoms of depression and anxiety. After that, she decided to keep me on the sertraline and mirtazapine, and she also upped the dose of propranolol to 15mg twice a day. She also added vraylar 15mg (which I was unable to ever take due to my Insurance refusing to cover it.) Additionally, she set me up for a meeting with the lead Psychiatrist for the following month. 

I just finished the Telehealth meeting with the the lead Psych, and I again expressed my dislike of the sertraline and propranolol. After hearing this, he doubled the dose of sertraline to 100mg daily and again increased the propranolol to 20mg twice a day. He also recommended that I take less of the mirtazapine (7.5mg nightly) to increase its effectiveness, and he suggested adding Abilify or rexulti to increase the effectiveness of the sertraline.  

I left the appointment feeling very defeated and like my concerns weren't being acknowledged. I really do want to believe that they are the professionals and they know what's best for me, but I just feel like they aren't listening to any of my concerns or opinions of the meds that I am on. 

So, naturally, I've come to reddit to inquire about what I should do. Should I just trust that they know what they are doing and continue to take the (expensive) perceptions that I find to be practically ineffective? Is it normal to feel like your meds aren't helping and will they begin to work after some more time has passed? I appreciate any helpful responses and direction on what I should do.
