I used to take Ativan as needed for panic attacks. It worked for me really well. I'd describe it as it didn't really take away whatever was making me panic, sometimes it happened for no reason and I was spiraling, but it made it so I no longer cared which was a weird feeling - but then I didn't care that it was weird. Like I was locking away the panicky part. It can also be used for sleep but it's a bit like using a bulldozer for a sand castle, overkill.

Its not a benzo (it's an SNRI) but I've also taken Effexor for OCD, which I found really useful. After a couple months, the things I obsessed over stopped mattering as much and I was able to start not checking even though I felt that same anxiety. I stopped after a little over a year and have been able to be off since with just CBT.
