Recently Castrated

Hi. I'm an older straight married male that was recently castrated not by choice. I went about a year without hrt. I enjoyed the calmness I felt but not the lack of energy or the weight gain. I'm currently on trt so I'm back to feeling the way I did before I was castrated. I'm not as happy as I was without hormones. Is it possible to be straight and take E and still have energy without weight gain? I would love to be straight on E. Thanks for your time.
