Made 1st call... was SO nervous. Adwice needed

Just now made my 1st scambait call. Completely new scambaiter here. I made an entire fake identity and got a TextNow account with a new gmail. Ran a VPN too and called with my laptop, but when I heard the voice on the other end, I got so nervous I couldn’t even speak, that never happened to me before. The call also sounded pretty legitimate, even though the number was posted here. I called the 1st number in this list:

ADV Soft:
18443074296
18665378008
18338080051
18002709908

Chawla Technical Support:
18558881542
18559993955
18336617666

Questions:
1) Is my current setup good and safe?
2) How to get past these nerves?

By the way, I got the list from Foreign_Hacker on this thread: http://scammer.info/d/38983-calls-wont-pickup
