Stop right there. You have a medical condition that needs treatment. No one earns medical care, it’s a necessity.
I agree with everything the other commenter said, thrift your clothes, and start with simple makeup. It will help you familiarize with women’s clothing sizes (they are nebulous), and what styles you enjoy. The more time you have practicing eyeliner, eye shadow blending, and blush placement, the better it will look when you’re ready to wear it in public and the more confident you will feel. I used to just sit with YouTube makeup tutorials and practice with them until I found things I liked
It has been many moons since I have done that, and I think both the platform and makeup looks have changed a bit. Also, you should look for someone with similar skin tone and basic facial structure. Learning how to do a cat eye is different for someone with deep set eyes versus hooded eyes.
That said, I am surprised to see Lisa Eldridge is still active, she has a lot of basic tutorial videos if you sort by oldest (omg has it really been 15 years?). A lot of the other ones I enjoyed seem to have deactivated their channels :(
