Help please!!!

I have been doing make up for the last three years and I'm having a hard time with my eyes!!! I've tried everything from watching YouTube (Jeffree, Manny, Laura, etc) and having someone who had taken cosmetology and is amazing at it try and teach me but I can't seem to get it 😥 I'm getting sick of just doing a single eye shadow color...I'm literally running out of colors 😄😂 I've tried doing a smokey eye and it turns out looking like I got punched in the eye 😢 and I can't do eye liner to save my life! I've tried using tape but I somehow still mess it up...don't get me wrong I like doing single color on the lid but I need a change...and Prom is next year and I would like to be able to do my own make up...Please if any of you have any tips and ideas that would be great...
