HCG and enclomiphene after years of testosterone use?

Hey guys, I have been on some level of testosterone for the past 3, almost 4 years, anywhere from 150-300mg/wk. I would really like to come off for multiple reasons but am a bit nervous how my “rebound” will be (both physically and mentally). My partner and I have been talking about having a child, I did an at home sperm count test a couple weeks ago and shocker-it was low. In the past I have delt with anxiety and depressive episodes most of my adult life but fortunately I don’t plan on those being too out of hand because I’m much happier with my life at this point compared to a couple years ago. I would just like to keep those to a minimum. Just looking for some advice to help get my levels back to normal, increase sperm production, keep up with my physical fitness, and keep me from wanting to jump off a bridge lol thanks in advance 👍🏼
