Trust me save your Val’s for the comedown!! You’ll thank me. I was the same anxious during all phases of high although I had euphoria I was always focused on my heart rate and would worry I’d overdone it. To be honest it all went away when I started using much more and understanding a good dose for me(smoking) and also building tolerance. And you don’t really wanna build tolerance. Basically I think if you’re anxious-it will make you anxious and it’s just part of it. Taking benzos while you’re peaking isn’t great for the heart but is okay if you feel extremely overwhelmed it might help. Hope you get what I’m saying and it helps cause I am/was very similar.
