Gonna repeat some advice: a good gender therapist can save your life.
I do a few things for the dysphoria. Underwear is the easiest thing -- nobody has to see it! Body hair is another -- if you were assigned female at birth, stop removing it; if you're assigned male at birth, start removing it. Again, you can cover this up with your clothes, and nobody needs to know.
In the beginning, "cross dressing" was hard because I looked so awful in everything I tried on. Some days, I stop at window shopping because the experience in the dressing room can be more painful than not trying. On stronger days, I've built up enough experience that I've found clothing styles that work for my pre-HRT body -- I expect it to be a couple of years before I feel comfortable looking in a mirror, but every little bit helps. My wardrobe is now 100% from my preferred gender, even though I'm not "out", and I no longer consider it cross dressing, and I feel alright about how I look despite being read as my birth-assigned gender by everybody I encounter.
Making progress towards transition helps. Once I made the decision to medically transition, my patience kicked in. As long as I could remember, I've had a very deep well of patience, so I'm lucky there. The ball is rolling, however slowly, and my dysphoria is almost gone except when I look in the mirror. When I get back from vacation, I have estrogen patches waiting for me at the pharmacy... that is such an awesome feeling! It'll be another two weeks after that before I get to take them, but whatever!
Transitioning socially helps. Some of my friends know. My wife calls me by my preferred name without fail now, except when we're with people who don't know. Wow, that's a huge help. Every time somebody uses my new name, it gives me a happy feeling. If you can find a group of people you've never met, and who will accept you for who you are, use your new name and never tell them your old name -- they might accidentally misgender you, they might forget your name, but they'll never call you by the wrong name.
