I effectively took a 'try HRT and see how you feel' approach myself, but it sounds like I was in a very different situation from you. I'd known I had gender identity issues for over 20 years, and I'd been debating transitioning for over a decade, but I was afraid of how I would be accepted, and whether I would ever pass, and whether I would ever feel safe again knowing some of the hate out there in the world. My dysphoria reached a point though where I was so miserable with my body and with my life as a guy that I was thinking about suicide on a daily basis, and years of therapy and multiple anti-depressants had done little to help. I started my 'trial approach' with the outlook that I was completely open to immediately starting on a full transition path if that's what felt right for me, and regardless of what else happened, I didn't see how I could possibly feel any worse than I did already, so what did I have to lose? Even if I decided later that transition wasn't for me, I was ok with the idea of living as a guy with small breasts, or being permanently sterile - given the state I was in, these were small things compared to the risk of leaving my dysphoria untreated.
One thing that might be helpful for you as it's a little lower risk (though not free of risk) is to try blockers alone or lower doses: I was on testosterone blockers alone for a few weeks before starting estradiol, and the blockers alone made a noticeable improvement in my mental state, and I got further improvement from my initial low dose of estradiol.
Given my own life situation, I felt like 'try and see what happens' was my only option, and thankfully it's made a massive improvement in my life. The only way I would ever recommend that approach to others though, is if you are fully aware of the potential consequences, and fully prepared to accept them. If that's not where you are in your journey right now, then I'd suggest trying other things to see if they help - talk to support groups, talk with a therapist, try experimenting with clothing or voice or mannerisms in a safe space, try interacting anonymously with people online as yourself (text, and if you feel comfortable with it, voice), whatever you think would be helpful for you.
