Drawing and Writing...along with music and reading

Ok so this is like two problems I'm having as of right now.

Lately I've been wanting to draw better. I know how to draw a little but it's bad. Like I can only draw a head and eyes sometimes hair but nothing else and that makes me so mad. I've tried watching tutorials and trying to find my own art style but nothings works so does anyone have any advice? I'm a traditional artist I've recently tried digital art but thats doesn't work for me at all.

Next is the writing topic. I've been writing for awhile now. I have drafts in my notes app but I can never get it right. I've tried searching up on Google and learning the fundamentals but it just isn't working. I just don't know how to put words together correctly or how to use the right words. I don't even know how I'm passing my FAST. I really do need help. I can't even write poems either. I have a lot of drafts sitting in every electronic I have and it pisses me off how I can never finish them. Like right now I feel like I'm being repetitive on what I'm typing. It's killing me! Anyone have advice?

Also it's the same thing with reading. Like whenever I'm reading it comes in one ear and out the other. I have to reread my favorite novel over and over again slowly. It's infuriating to me! Especially when I see videos of people getting the plot and I don't understand it even when it's laid right in front of me! I just can't comprehend anything!

I think I'm just slow or really retarded. I don't know what to do really! Anyone have any advice on how I can fix my flaws or compression? I really enjoy drawing, writing and reading I can just never really focus.

Right and one more question. Ugh I'm just yapping at this point. Any musical artist out there? I'm trying to learn how to make proper music. I made some drafts but I don't like them at all. Is it the same as writing and reading? Thats a dumb question I just asked ignore that. But do I have to like grasp the essence of writing? I don't understand anything. I don't even understand myself anymore.
