Hello Disco girl.
It happened to me too.I think its the way our system absorbes the gel, maybe too fast, it plumed too fast and the increase anxiety appears.
It was horrible, I couldn't handle the stress at work. I tried 1 pump, 0,5 pump (anxiety around 2 hours later) and 2 pumps. With 2 pumps the anxiety came at around 5pm.
It didn't happen when I was taken Femoston 2/10 (oral.oestrogen).
