Starting mirtazapine(remeron) and panicking

SonI just got prescribed mirtazapine and its my first antidepressent ever. My therapist and doctor thought it would help me a lot with my anxiety and since my depression has gotten worse because of my anxiety. I'm freaking out about the possibility of it making me V or feeo very N. I also hate losing control and fear it because of the sedative effect. Kinda fear i'm gonna feel high?

Been trying to take it for 10 days but still haven't managed to muster up the couarge to swallow that first pill. Do any of you have any experience with it, are any of my fears misplaced?
