Honeydew Syndrome
Altho it's a bit more emo than goth but I hope u try it anyway ^^
I read the part where you wanted to be goth, well, if you truly are interested, you should keep on trying even if you cant get it right the first time(make-up) but the more you use it the more better you get. Also there are a lot of make up tutorials nowadays on utube so you can watch while trying. Also as for the necessary products, you should google what you needs and survey the malls for an appropriate price for you to buy. Dont give up. If you want it, you should do it!~
The only one I know they call goth is this http://www.mangago.zone/read-manga/twins_labyrinth/an/twins-labyrinth-chapter-7.html (it's probably not what you meant, but there're different types of goth)
Do you want to be goth or just like the look? Bc goth is not only make up, it's more about music, attitude, stuff like that.
You don't have to go fully white, you can always try Siouxsie's look (or Peter Murphy's from The Hunger ლ(´ڡ`ლ) )
I believe they use white foundation (if it's for a party or sth white face paint would do) and powder. Eye make up shouldn't be so hard as it's thick, so it doesn't have to be perfect.
There are many tutorials on YT, I know It's Black Friday makes them too, you can check her out.
These characters have a gothic look imo:

Okay, so any really gothic looking characters in yaoi?
Also, for quite a few years, I've wanted to put on the goth look, unfortunately, I'm broke, and I'm shit at make up
The fuck am I meant to do like? I can't even do one eyebrow never mind perfect eye make up, and I have no idea how to get the white skin, is it face paint or what?
