Your body probably doesn't know what to do with the new hormones. I'm surprised you felt amped as it takes most people 4-6 weeks to feel anything. I took me about 4. The anxiety could be due to the fluctuating hormone dosages and also the E conversion. Stick with the 120mg twice a week protocol and not the first one. Since you already started on the AI, stick with the 1mg a week spread out or at least take half the dose with each injection. Then give yourself some time to even out and try not to stress. Could be placebo/stress.
