What you're seeing through all the responses is that our community is willing to take risks for the good of others. And, that we know that we help lift ourselves when we lift another. It's part of what helped me when I started my transition and still is there for me when I need it occasionally.
And the good news? It's there for you, as well.
Until you are ready to venture out, YouTube and the advice you garner in places like this can be your "go-to" on applying make-up. My basic routine takes no more than 20 minutes, unless I'm going for a more glamorous look (Heck, how glamorous can a 70 year old get? lol). As you see me in my profile is my "usual." A bit of orange color corrector to hide the remaining shadow on my upper lip, Mary Kay Creame to Powder foundation followed by powder to set it, pewter eyebrow pencil, gel eye liner pencil for my eyes, mascara, just a bit of rouge to highlight my cheek bones and, lastly, lipstick. That all may sound daunting but you'll learn it. I'm never going to be a gorgeous model or actress. My goal is to look presentable. To look in the mirror and smile at the woman I see looking back at me. Simple.
One possibility is to search around you for both a LGBTQ+ resource center as well as any local crossdresser groups. You will be amazed at how many people cross dress on a routine basis - even deep in the Bible Belt. There's a convention in Atlanta - might be this week - where they have a multi-day get together to socialize. Either community might be a way to find hands-on assistance with make-up. I can't tell you how many wonderful friends I've made among the CD community and how open and helpful they are, just like the TG community.
Another option would be to look for a Sephora store somewhere far enough away that you'd feel (even somewhat) comfortable going to. They often schedule times to help members of the TG/CD community learn to apply make-up. Honestly, you could even walk into one and they will help, but they often will schedule individual appointments on Saturday mornings or some other time when they are not open to regular customers.
Finally, have you considered working with a gender therapist to help establish your path forward? I may have missed you mentioning it so forgive me if I have. Many of us have found it to be invaluable. I've worked with mine for over 2 years now and she has been a life-saver for me as well as a catalyst to putting the dysphoria in check and embracing my reality. We've met totally through video sessions - she lives over 600 miles away. Again, you may find a local or regional LGBTQ+ center or website with suggested providers.
Just some thoughts for you to consider. The hardest part is gaining the courage to reach out, to get out and begin to live your life. You'll get there.
