TLDR at end
I (22 F) have had severe anxiety basically my whole life. Meds were mostly working for me until 2020 when a lot of traumatic stuff happened. Since then, it’s been hard to find a combo that consistently works for me. 
My psychiatrist thinks I’d benefit from a low dosage benzo, but i am terrified of them lol. There’s a history of drug and alcohol addiction in my family so i steer clear of alcohol &amp; any meds that are habit-forming. 
When I was diagnosed with ADHD last year, it was even a struggle to force myself to take vyvanse. 
I’ve been very panicky for about a month as my grandpa who i was close to died. I quit my shitty retail job because they gave me shit about having to miss work to travel from NC to NY for his funeral. College semester wrapped up in april so there’s 0 structure in my day to day life.  I dont handle change well so it makes me incredibly nervous and panicky. 
I’ve been on probably every anxiety medication under the sun. For a while now, i’ve been on zoloft &amp; welbutrin (along with adhd meds like vyvanse) and i thought they were working, but then all of this stuff happened &amp; now I’m buggin out every day. 
How do I get over the fear of becoming addicted to benzos that im pretty sure would make my life more manageable?

TLDR: I’ve been panicky for a month straight after a change in schedule and some trauma and my psychiatrist recommends trying a low dosage benzo. But i’m terrified bc there’s a history of drug abuse in my family. How do I get over it and just take the meds?
