You need confidence, because you have the passion (it's the thing telling you that you want to better than what you are).
I started digitally, but I'd recommend any artist go the easy route and research traditional basics prior to creating anything but illustration on a graphics tablet. This tablet works wonders but your workspace is crucial and a digital one, especially connected to the internet, is going to throw off focus. When I'm doing anything digitally creative I turn off my wi-fi switch.
I carry a Memorax everywhere in my pocket. There are times you sit to draw but can't think of anything. That's because inspiration comes with your daily exploration so any time you see something and you say "wow that'd be cool if it looked like this instead", jot down the idea (I like to add notes about any techniques I might need to use.
Research is important, in the beginning it took equal as long as the commission. As I produce more, things become ritual and require less time.
A basic drawing set, geometric shape and still life drawing, using only micro circles to shade instead of trying to go side to side, quality materials, and some books on anatomy should do you good. Start copying things from life, keep these as studies. Try to copy photographs exactly as they look when you're dedicating time to art but balance doing creative art for yourself as well. Good luck!
